Changes for Linux 5.2: 

- Fix some more buffer deadlocks when performing an unmount after a hard
   shutdown.
 - Fix some minor space accounting issues.
 - Fix some use after free problems.
 - Make the (undocumented) FITRIM behavior consistent with other filesystems.
 - Embiggen the xfs geometry ioctl's data structure.
 - Introduce a new AG geometry ioctl.
 - Introduce a new online health reporting infrastructure and ioctl for
   userspace to query a filesystem's health status.
 - Enhance online scrub and repair to update the health reports.
 - Reduce thundering herd problems when writeback io completes.
 - Fix some transaction reservation type errors.
 - Fix integer overflow problems with delayed alloc reservation counters.
 - Fix some problems where we would exit to userspace without unlocking.
 - Fix inconsistent behavior when finishing deferred ops fails.
 - Strengthen scrub to check incore data against ondisk metadata.
 - Remove long-broken mntpt mount option.
 - Add an online scrub function for the filesystem summary counters,
   which should make online metadata scrub more or less feature complete
   for now.
 - Various cleanups.

Merge tag 'xfs-5.2-merge-4' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux

Pull xfs updates from Darrick Wong:
 "Here's a big pile of new stuff for XFS for 5.2. XFS has grown the
  ability to report metadata health status to userspace after online
  fsck checks the filesystem. The online metadata checking code is (I
  really hope) feature complete with the addition of checks for the
  global fs counters, though it'll remain EXPERIMENTAL for now.

  There are also fixes for thundering herds of writeback completions and
  some other deadlocks, fixes for theoretical integer overflow attacks
  on space accounting, and removal of the long-defunct 'mntpt' option
  which was deprecated in the mid-2000s and (it turns out) totally
  broken since 2011 (and nobody complained...).

  Summary:

   - Fix some more buffer deadlocks when performing an unmount after a
     hard shutdown.

   - Fix some minor space accounting issues.

   - Fix some use after free problems.

   - Make the (undocumented) FITRIM behavior consistent with other
     filesystems.

   - Embiggen the xfs geometry ioctl's data structure.

   - Introduce a new AG geometry ioctl.

   - Introduce a new online health reporting infrastructure and ioctl
     for userspace to query a filesystem's health status.

   - Enhance online scrub and repair to update the health reports.

   - Reduce thundering herd problems when writeback io completes.

   - Fix some transaction reservation type errors.

   - Fix integer overflow problems with delayed alloc reservation
     counters.

   - Fix some problems where we would exit to userspace without
     unlocking.

   - Fix inconsistent behavior when finishing deferred ops fails.

   - Strengthen scrub to check incore data against ondisk metadata.

   - Remove long-broken mntpt mount option.

   - Add an online scrub function for the filesystem summary counters,
     which should make online metadata scrub more or less feature
     complete for now.

   - Various cleanups"

* In-Core Filesystem Health Assessments
* =====================================
*
* We'd like to be able to summarize the current health status of the
* filesystem so that the administrator knows when it's necessary to schedule
* some downtime for repairs. Until then, we would also like to avoid abrupt
* shutdowns due to corrupt metadata.
*
* The online scrub feature evaluates the health of all filesystem metadata.
* When scrub detects corruption in a piece of metadata it will set the
* corresponding sickness flag, and repair will clear it if successful. If
* problems remain at unmount time, we can also request manual intervention by
* logging a notice to run xfs_repair.
*
* Each health tracking group uses a pair of fields for reporting. The
* "checked" field tell us if a given piece of metadata has ever been examined,
* and the "sick" field tells us if that piece was found to need repairs.
* Therefore we can conclude that for a given sick flag value:
*
* - checked && sick => metadata needs repair
* - checked && !sick => metadata is ok
* - !checked => has not been examined since mount

* FS Summary Counters
* ===================
*
* The basics of filesystem summary counter checking are that we iterate the
* AGs counting the number of free blocks, free space btree blocks, per-AG
* reservations, inodes, delayed allocation reservations, and free inodes.
* Then we compare what we computed against the in-core counters.
*
* However, the reality is that summary counters are a tricky beast to check.
* While we /could/ freeze the filesystem and scramble around the AGs counting
* the free blocks, in practice we prefer not do that for a scan because
* freezing is costly. To get around this, we added a per-cpu counter of the
* delalloc reservations so that we can rotor around the AGs relatively
* quickly, and we allow the counts to be slightly off because we're not taking
* any locks while we do this.
*
* So the first thing we do is warm up the buffer cache in the setup routine by
* walking all the AGs to make sure the incore per-AG structure has been
* initialized. The expected value calculation then iterates the incore per-AG
* structures as quickly as it can. We snapshot the percpu counters before and
* after this operation and use the difference in counter values to guess at
* our tolerance for mismatch between expected and actual counter values.
*/
/*
* Since the expected value computation is lockless but only browses incore
* values, the percpu counters should be fairly close to each other. However,
* we'll allow ourselves to be off by at least this (arbitrary) amount.

* summary counters after checking all AG headers). Do this from the setup
* function so that the inner AG aggregation loop runs as quickly as possible.
*
* This function runs during the setup phase /before/ we start checking any

* Scrub and In-Core Filesystem Health Assessments
* ===============================================
*
* Online scrub and repair have the time and the ability to perform stronger
* checks than we can do from the metadata verifiers, because they can
* cross-reference records between data structures. Therefore, scrub is in a
* good position to update the online filesystem health assessments to reflect
* the good/bad state of the data structure.
*
* We therefore extend scrub in the following ways to achieve this:
*
* 1. Create a "sick_mask" field in the scrub context. When we're setting up a
* scrub call, set this to the default XFS_SICK_* flag(s) for the selected
* scrub type (call it A). Scrub and repair functions can override the default
* sick_mask value if they choose.
*
* 2. If the scrubber returns a runtime error code, we exit making no changes
* to the incore sick state.
*
* 3. If the scrubber finds that A is clean, use sick_mask to clear the incore
* sick flags before exiting.
*
* 4. If the scrubber finds that A is corrupt, use sick_mask to set the incore
* sick flags. If the user didn't want to repair then we exit, leaving the
* metadata structure unfixed and the sick flag set.
*
* 5. Now we know that A is corrupt and the user wants to repair, so run the
* repairer. If the repairer returns an error code, we exit with that error
* code, having made no further changes to the incore sick state.
*
* 6. If repair rebuilds A correctly and the subsequent re-scrub of A is clean,
* use sick_mask to clear the incore sick flags. This should have the effect
* that A is no longer marked sick.
*
* 7. If repair rebuilds A incorrectly, the re-scrub will find it corrupt and
* use sick_mask to set the incore sick flags. This should have no externally
* visible effect since we already set them in step (4).
*
* There are some complications to this story, however. For certain types of
* complementary metadata indices (e.g. inobt/finobt), it is easier to rebuild
* both structures at the same time. The following principles apply to this
* type of repair strategy:
*
* 8. Any repair function that rebuilds multiple structures should update
* sick_mask_visible to reflect whatever other structures are rebuilt, and
* verify that all the rebuilt structures can pass a scrub check. The outcomes
* of 5-7 still apply, but with a sick_mask that covers everything being
* rebuilt.
