Add a memory.swap.high knob, which can be used to protect the system
from SWAP exhaustion. The mechanism used for penalizing is similar to
memory.high penalty (sleep on return to user space).
That is not to say that the knob itself is equivalent to memory.high.
The objective is more to protect the system from potentially buggy tasks
consuming a lot of swap and impacting other tasks, or even bringing the
whole system to stand still with complete SWAP exhaustion. Hopefully
without the need to find per-task hard limits.
Slowing misbehaving tasks down gradually allows user space oom killers
or other protection mechanisms to react. oomd and earlyoom already do
killing based on swap exhaustion, and memory.swap.high protection will
help implement such userspace oom policies more reliably.
We can use one counter for number of pages allocated under pressure to
save struct task space and avoid two separate hierarchy walks on the hot
path. The exact overage is calculated on return to user space, anyway.
Take the new high limit into account when determining if swap is "full".
Borrowing the explanation from Johannes:
The idea behind "swap full" is that as long as the workload has plenty
of swap space available and it's not changing its memory contents, it
makes sense to generously hold on to copies of data in the swap device,
even after the swapin. A later reclaim cycle can drop the page without
any IO. Trading disk space for IO.
But the only two ways to reclaim a swap slot is when they're faulted
in and the references go away, or by scanning the virtual address space
like swapoff does - which is very expensive (one could argue it's too
expensive even for swapoff, it's often more practical to just reboot).
So at some point in the fill level, we have to start freeing up swap
slots on fault/swapin. Otherwise we could eventually run out of swap
slots while they're filled with copies of data that is also in RAM.
We don't want to OOM a workload because its available swap space is
filled with redundant cache.

There's a new workingset counter introduced in commit 1899ad18c6 ("mm:
workingset: tell cache transitions from workingset thrashing"). With
the help of this counter we can know the workingset is transitioning or
thrashing. To leverage the benifit of this counter to memcg, we should
introduce it into memory.stat. Then we could know the workingset of the
workload inside a memcg better.
Bellow is the verification of this new counter in memory.stat. Read a
file into the memory and then read it again to make these pages be
active. The size of this file is 1G. (memory.max is greater than file
size) The counters in memory.stat will be
inactive_file 0
active_file 1073639424
workingset_refault 0
workingset_activate 0
workingset_restore 0
workingset_nodereclaim 0
Trigger the memcg reclaim by setting a lower value to memory.high, and
then some pages will be demoted into inactive list, and then some pages
in the inactive list will be evicted into the storage.
inactive_file 498094080
active_file 310063104
workingset_refault 0
workingset_activate 0
workingset_restore 0
workingset_nodereclaim 0
Then recover the memory.high and read the file into memory again. As a
result of it, the transitioning will occur. Bellow is the result of
this transitioning,
inactive_file 498094080
active_file 575397888
workingset_refault 64746
workingset_activate 64746
workingset_restore 64746

After an NFS page has been written it is considered "unstable" until a
COMMIT request succeeds. If the COMMIT fails, the page will be
re-written.
These "unstable" pages are currently accounted as "reclaimable", either
in WB_RECLAIMABLE, or in NR_UNSTABLE_NFS which is included in a
'reclaimable' count. This might have made sense when sending the COMMIT
required a separate action by the VFS/MM (e.g. releasepage() used to
send a COMMIT). However now that all writes generated by ->writepages()
will automatically be followed by a COMMIT (since commit 919e3bd9a8
("NFS: Ensure we commit after writeback is complete")) it makes more
sense to treat them as writeback pages.
So this patch removes NR_UNSTABLE_NFS and accounts unstable pages in
NR_WRITEBACK and WB_WRITEBACK.
A particular effect of this change is that when
wb_check_background_flush() calls wb_over_bg_threshold(), the latter
will report 'true' a lot less often as the 'unstable' pages are no
longer considered 'dirty' (as there is nothing that writeback can do
about them anyway).
Currently wb_check_background_flush() will trigger writeback to NFS even
when there are relatively few dirty pages (if there are lots of unstable
pages), this can result in small writes going to the server (10s of
Kilobytes rather than a Megabyte) which hurts throughput. With this
patch, there are fewer writes which are each larger on average.
Where the NR_UNSTABLE_NFS count was included in statistics
virtual-files, the entry is retained, but the value is hard-coded as
zero. static trace points and warning printks which mentioned this
counter no longer report it.

This replaces ->readpages with a saner interface:
- Return void instead of an ignored error code.
- Page cache is already populated with locked pages when ->readahead
is called.
- New arguments can be passed to the implementation without changing
all the filesystems that use a common helper function like
mpage_readahead().

set from Mauro toward the completion of the RST conversion. I *really*
hope we are getting close to the end of this. Meanwhile, those patches
reach pretty far afield to update document references around the tree;
there should be no actual code changes there. There will be, alas, more of
the usual trivial merge conflicts.
Beyond that we have more translations, improvements to the sphinx
scripting, a number of additions to the sysctl documentation, and lots of
fixes.

Pull documentation updates from Jonathan Corbet:
"A fair amount of stuff this time around, dominated by yet another
massive set from Mauro toward the completion of the RST conversion. I
*really* hope we are getting close to the end of this. Meanwhile,
those patches reach pretty far afield to update document references
around the tree; there should be no actual code changes there. There
will be, alas, more of the usual trivial merge conflicts.
Beyond that we have more translations, improvements to the sphinx
scripting, a number of additions to the sysctl documentation, and lots
of fixes"

- Branch Target Identification (BTI)
* Support for ARMv8.5-BTI in both user- and kernel-space. This
allows branch targets to limit the types of branch from which
they can be called and additionally prevents branching to
arbitrary code, although kernel support requires a very recent
toolchain.
* Function annotation via SYM_FUNC_START() so that assembly
functions are wrapped with the relevant "landing pad"
instructions.
* BPF and vDSO updates to use the new instructions.
* Addition of a new HWCAP and exposure of BTI capability to
userspace via ID register emulation, along with ELF loader
support for the BTI feature in .note.gnu.property.
* Non-critical fixes to CFI unwind annotations in the sigreturn
trampoline.
- Shadow Call Stack (SCS)
* Support for Clang's Shadow Call Stack feature, which reserves
platform register x18 to point at a separate stack for each
task that holds only return addresses. This protects function
return control flow from buffer overruns on the main stack.
* Save/restore of x18 across problematic boundaries (user-mode,
hypervisor, EFI, suspend, etc).
* Core support for SCS, should other architectures want to use it
too.
* SCS overflow checking on context-switch as part of the existing
stack limit check if CONFIG_SCHED_STACK_END_CHECK=y.
- CPU feature detection
* Removed numerous "SANITY CHECK" errors when running on a system
with mismatched AArch32 support at EL1. This is primarily a
concern for KVM, which disabled support for 32-bit guests on
such a system.

"A sizeable pile of arm64 updates for 5.8.
Summary below, but the big two features are support for Branch Target
Identification and Clang's Shadow Call stack. The latter is currently
arm64-only, but the high-level parts are all in core code so it could
easily be adopted by other architectures pending toolchain support

of local_lock_t - this primitive comes from the -rt project and identifies
CPU-local locking dependencies normally handled opaquely beind preempt_disable()
or local_irq_save/disable() critical sections.
The generated code on mainline kernels doesn't change as a result, but still there
are benefits: improved debugging and better documentation of data structure
accesses.
The new local_lock_t primitives are introduced and then utilized in a couple of
kernel subsystems. No change in functionality is intended.
There's also other smaller changes and cleanups.

The big change in this release is that Matti Vaittinen has factored out
the linear ranges support into a separate library in lib/ since it is
also useful for at least the power subsystem (and most likely others
too), it helps subsystems which need to map register values into more
useful real world values do so with minimal per-driver code.

This has been a very active release for the DesignWare driver in
particular - after a long period of inactivity we have had a lot of
people actively working on it for unrelated reasons this cycle with some
of that work still not landed. Otherwise it's been fairly quiet for the
subsystem. Highlights include:
- Lots of performance improvements and fixes for the DesignWare driver
from Serge Semin, Andy Shevchenko, Wan Ahmad Zainie, Clement Leger,
Dinh Nguyen and Jarkko Nikula.
- Support for octal mode transfers in spidev.
- Slave mode support for the Rockchip drivers.
- Support for AMD controllers, Broadcom mspi and Raspberry Pi 4,
and Intel Elkhart Lake.

Recently, I switched over from swap-file to zramswap.
When reading the Documentation/vm/zswap.rst file I fell over this typo.
The parameter is called accept_threshold_percent not accept_threhsold_percent
in /sys/module/zswap/parameters/ directory.
Fixes: 45190f01dd ("mm/zswap.c: add allocation hysteresis if pool limit is hit")

This introduces mtdpstore, which is similar to mtdoops but more
powerful. It uses pstore/blk, and aims to store panic and oops logs to
a flash partition, where pstore can later read back and present as files
in the mounted pstore filesystem.
To make mtdpstore work, the "blkdev" of pstore/blk should be set
as MTD device name or MTD device number. For more details, see
Documentation/admin-guide/pstore-blk.rst
This solves a number of issues:
- Work duplication: both of pstore and mtdoops do the same job storing
panic/oops log. They have very similar logic, registering to kmsg
dumper and storing logs to several chunks one by one.
- Layer violations: drivers should provides methods instead of polices.
MTD should provide read/write/erase operations, and allow a higher
level drivers to provide the chunk management, kmsg dump
configuration, etc.
- Missing features: pstore provides many additional features, including
presenting the logs as files, logging dump time and count, and
supporting other frontends like pmsg, console, etc.

Add support for non-block devices (e.g. MTD). A non-block driver calls
pstore_blk_register_device() to register iself.
In addition, pstore/zone is updated to handle non-block devices,
where an erase must be done before a write. Without this, there is no
way to remove records stored to an MTD.

Yes, staying withing 80 columns is certainly still _preferred_. But
it's not the hard limit that the checkpatch warnings imply, and other
concerns can most certainly dominate.
Increase the default limit to 100 characters. Not because 100
characters is some hard limit either, but that's certainly a "what are
you doing" kind of value and less likely to be about the occasional
slightly longer lines.
Miscellanea:
- to avoid unnecessary whitespace changes in files, checkpatch will no
longer emit a warning about line length when scanning files unless
--strict is also used
- Add a bit to coding-style about alignment to open parenthesis

Currently, it is only possible to get kmsg dumps for panic and oops,
or just panic, via "no-dump-oops". With "max-reason" it is possible to
dump messages for other kmsg_dump events, for example emerg and shutdown.

Now that pstore_register() can correctly pass max_reason to the kmesg
dump facility, introduce a new "max_reason" module parameter and
"max-reason" Device Tree field.
The "dump_oops" module parameter and "dump-oops" Device
Tree field are now considered deprecated, but are now automatically
converted to their corresponding max_reason values when present, though
the new max_reason setting has precedence.
For struct ramoops_platform_data, the "dump_oops" member is entirely
replaced by a new "max_reason" member, with the only existing user
updated in place.
Additionally remove the "reason" filter logic from ramoops_pstore_write(),
as that is not specifically needed anymore, though technically
this is a change in behavior for any ramoops users also setting the
printk.always_kmsg_dump boot param, which will cause ramoops to behave as
if max_reason was set to KMSG_DUMP_MAX.

Modern device tree bindings are supposed to be created as YAML-files
in accordance with dt-schema. This commit replaces two DW SPI legacy
bare text bindings with YAML file. As before the bindings file states
that the corresponding dts node is supposed to be compatible either
with generic DW APB SSI controller or with Microsemi/Amazon/Renesas/Intel
vendors-specific controllers, to have registers, interrupts and clocks
properties. Though in case of Microsemi version of the controller
there must be two registers resources specified. Properties like
clock-names, reg-io-width, cs-gpio, num-cs, DMA and slave device
sub-nodes are optional.
