If the mount is aborted after userspace has been asked to mount,
userspace must be told to unmount.
Ordinarily orangefs_kill_sb does the unmount. However it cannot be
called if the superblock has not been set up. This is a very narrow
window.
The NULL fs_id is not unmounted.

Let the server figure this out because our size might be out of date or
not present.
The bug was that
xfs_io -f -t -c "pread -v 0 100" /mnt/foo
echo "Test" > /mnt/foo
xfs_io -f -t -c "pread -v 0 100" /mnt/foo
fails because the second truncate did not happen if nothing had
requested the size after the write in echo. Thus i_size was zero (not
present) and the orangefs_setattr though i_size was zero and there was
nothing to do.

Fortunately OrangeFS has had a getattr request mask for a long time.
The server basically has two difficulty levels for attributes. Fetching
any attribute except size requires communicating with the metadata
server for that handle. Since all the attributes are right there, it
makes sense to return them all. Fetching the size requires
communicating with every I/O server (that the file is distributed
across). Therefore if asked for anything except size, get everything
except size, and if asked for size, get everything.

This works by maintaining a linked list of pages which the directory
has been read into rather than one giant fixed-size buffer.
This replaces code which limits the total directory size to the total
amount that could be returned in one server request. Since filenames
are usually considerably shorter than the maximum, the old code could
usually handle several server requests before running out of space.

In the past, readdir assumed that the user buffer will be large enough

Maps of per-cpu type have their value element size adjusted to 8 if it
is specified smaller during various map operations.
This makes test_maps as a 32-bit binary fail, in fact the kernel
writes past the end of the value's array on the user's stack.
To be quite honest, I think the kernel should reject creation of a
per-cpu map that doesn't have a value size of at least 8 if that's
what the kernel is going to silently adjust to later.
If the user passed something smaller, it is a sizeof() calcualtion
based upon the type they will actually use (just like in this testcase
code) in later calls to the map operations.

Andrey's syzkaller program passes rtmsg.rtmsg_flags with the RTF_PCPU bit
set. Flags passed to the kernel are blindly copied to the allocated
rt6_info by ip6_route_info_create making a newly inserted route appear
as though it is a per-cpu route. ip6_rt_cache_alloc sees the flag set
and expects rt->dst.from to be set - which it is not since it is not
really a per-cpu copy. The subsequent call to __ip6_dst_alloc then
generates the fault.
Fix by checking for the flag and failing with EINVAL.

Commit 07b26c9454 ("gso: Support partial splitting at the frag_list
pointer") assumes that all SKBs in a frag_list (except maybe the last
one) contain the same amount of GSO payload.
This assumption is not always correct, resulting in the following
warning message in the log:
skb_segment: too many frags
For example, mlx5 driver in Striding RQ mode creates some RX SKBs with
one frag, and some with 2 frags.
After GRO, the frag_list SKBs end up having different amounts of payload.
If this frag_list SKB is then forwarded, the aforementioned assumption
is violated.
Validate the assumption, and fall back to software GSO if it not true.

mm: prevent NR_ISOLATE_* stats from going negative
Revert "mm, page_alloc: only use per-cpu allocator for irq-safe requests"
Commit 6afcf8ef0c ("mm, compaction: fix NR_ISOLATED_* stats for pfn
based migration") moved the dec_node_page_state() call (along with the
page_is_file_cache() call) to after putback_lru_page().
But page_is_file_cache() can change after putback_lru_page() is called,
so it should be called before putback_lru_page(), as it was before that
patch, to prevent NR_ISOLATE_* stats from going negative.
Without this fix, non-CONFIG_SMP kernels end up hanging in the
while(too_many_isolated()) { congestion_wait() } loop in
shrink_active_list() due to the negative stats.

This reverts commit 374ad05ab6.
While the patch worked great for userspace allocations, the fact that
softirq loses the per-cpu allocator caused problems. It needs to be
redone taking into account that a separate list is needed for hard/soft
IRQs or alternatively find a cheap way of detecting reentry due to an
interrupt. Both are possible but sufficiently tricky that it shouldn't
be rushed.
Jesper had one method for allowing softirqs but reported that the cost
was high enough that it performed similarly to a plain revert. His
figures for netperf TCP_STREAM were as follows
Baseline v4.10.0 : 60316 Mbit/s
Current 4.11.0-rc6: 47491 Mbit/s
Jesper's patch : 60662 Mbit/s
This patch : 60106 Mbit/s
As this is a regression, I wish to revert to noirq allocator for now and
go back to the drawing board.

If we have a scheduler attached, blk_mq_tag_to_rq() on the
scheduled tags will return NULL if a request is no longer
in flight. This is different than using the normal tags,
where it will always return the fixed request. Check for
this condition for polling, in case we happen to enter
polling for a completed request.
The request address remains valid, so this check and return
should be perfectly safe.

I got a couple more reports: the Samsung APST issues appears to
affect multiple 950-series devices in Dell XPS 15 9550 and Precision
5510 laptops. Change the quirk: rather than blacklisting the
firmware on the first problematic SSD that was reported, disable
APST on all 144d:a802 devices if they're installed in the two
affected Dell models. While we're at it, disable only the deepest
sleep state instead of all of them -- the reporters say that this is
sufficient to fix the problem.
(I have a device that appears to be entirely identical to one of the
affected devices, but I have a different Dell laptop, so it's not
the case that all Samsung devices with firmware BXW75D0Q are broken
under all circumstances.)
Samsung engineers have an affected system, and hopefully they'll
give us a better workaround some time soon. In the mean time, this
should minimize regressions.

Policing filters do not use the TCA_ACT_* enum and the tb[]
nlattr array in tcf_action_init_1() doesn't get filled for
them so we should not try to look for a TCA_ACT_COOKIE
attribute in the then uninitialized array.
The error handling in cookie allocation then calls
tcf_hash_release() leading to invalid memory access later
on.
Additionally, if cookie allocation fails after an already
existing non-policing filter has successfully been changed,
tcf_action_release() should not be called, also we would
have to roll back the changes in the error handling, so
instead we now allocate the cookie early and assign it on
success at the end.
