Pull xfs updates from Darrick Wong: "There's a lot in this cycle.
Starting with bug fixes: To avoid livelocks between the logging code and the quota code, we've disabled the ability of quotaoff to turn off quota accounting. (Admins can still disable quota enforcement, but truly turning off accounting requires a remount.) We've tried to do this in a careful enough way that there shouldn't be any user visible effects aside from quotaoff no longer randomly hanging the system.
We've also fixed some bugs in runtime log behavior that could trip up log recovery if (otherwise unrelated) transactions manage to start and commit concurrently; some bugs in the GETFSMAP ioctl where we would incorrectly restrict the range of records output if the two xfs devices are of different sizes; a bug that resulted in fallocate funshare failing unnecessarily; and broken behavior in the xfs inode cache when DONTCACHE is in play.
As for new features: we now batch inode inactivations in percpu background threads, which sharply decreases frontend thread wait time when performing file deletions and should improve overall directory tree deletion times. This eliminates both the problem where closing an unlinked file (especially on a frozen fs) can stall for a long time, and should also ease complaints about direct reclaim bogging down on unlinked file cleanup.
Starting with this release, we've enabled pipelining of the XFS log. On workloads with high rates of metadata updates to different shards of the filesystem, multiple threads can be used to format committed log updates into log checkpoints.
Lastly, with this release, two new features have graduated to supported status: inode btree counters (for faster mounts), and support for dates beyond Y2038. Expect these to be enabled by default in a future release of xfsprogs.
Summary:
- Fix a potential log livelock on busy filesystems when there's so much work going on that we can't finish a quotaoff before filling up the log by removing the ability to disable quota accounting.
- Introduce the ability to use per-CPU data structures in XFS so that we can do a better job of maintaining CPU locality for certain operations.
- Defer inode inactivation work to per-CPU lists, which will help us batch that processing. Deletions of large sparse files will *appear* to run faster, but all that means is that we've moved the work to the backend.
- Drop the EXPERIMENTAL warnings from the y2038+ support and the inode btree counters, since it's been nearly a year and no complaints have come in.
- Remove more of our bespoke kmem* variants in favor of using the standard Linux calls.
- Prepare for the addition of log incompat features in upcoming cycles by actually adding code to support this.
- Small cleanups of the xattr code in preparation for landing support for full logging of extended attribute updates in a future cycle.
- Replace the various log shutdown state and flag code all over xfs with a single atomic bit flag.
- Fix a serious log recovery bug where log item replay can be skipped based on the start lsn of a transaction even though the transaction commit lsn is the key data point for that by enforcing start lsns to appear in the log in the same order as commit lsns.
- Enable pipelining in the code that pushes log items to disk.
- Drop ->writepage.
- Fix some bugs in GETFSMAP where the last fsmap record reported for a device could extend beyond the end of the device, and a separate bug where query keys for one device could be applied to another.
- Don't let GETFSMAP query functions edit their input parameters.
- Small cleanups to the scrub code's handling of perag structures.
- Small cleanups to the incore inode tree walk code.
- Constify btree function parameters that aren't changed, so that there will never again be confusion about range query functions changing their input parameters.
- Standardize the format and names of tracepoint data attributes.
- Clean up all the mount state and feature flags to use wrapped bitset functions instead of inconsistently open-coded flag checks.
- Fix some confusion between xfs_buf hash table key variable vs. block number.
- Fix a mis-interaction with iomap where we reported shared delalloc cow fork extents to iomap, which would cause the iomap unshare operation to return IO errors unnecessarily.
- Fix DONTCACHE behavior"

xfs: replace xfs_sb_version checks with feature flag checks
Convert the xfs_sb_version_hasfoo() to checks against mp->m_features. Checks of the superblock itself during disk operations (e.g. in the read/write verifiers and the to/from disk formatters) are not converted - they operate purely on the superblock state. Everything else should use the mount features.
Large parts of this conversion were done with sed with commands like this:
for f in `git grep -l xfs_sb_version_has fs/xfs/*.c`; do sed -i -e 's/xfs_sb_version_has\(.*\)(&\(.*\)->m_sb)/xfs_has_\1(\2)/' $f done
With manual cleanups for things like "xfs_has_extflgbit" and other little inconsistencies in naming.
The result is ia lot less typing to check features and an XFS binary size reduced by a bit over 3kB:

Pull xfs updates from Darrick Wong: "Most of the work this cycle has been on refactoring various parts of the codebase. The biggest non-cleanup changes are (1) reducing the number of cache flushes sent when writing the log; (2) a substantial number of log recovery fixes; and (3) I started accepting pull requests from contributors if the commits in their branches match what's been sent to the list.
For a week or so I /had/ staged a major cleanup of the logging code from Dave Chinner, but it exposed so many lurking bugs in other parts of the logging and log recovery code that I decided to defer that patchset until we can address those latent bugs.
Larger cleanups this time include walking the incore inode cache (me) and rework of the extended attribute code (Allison) to prepare it for adding logged xattr updates (and directory tree parent pointers) in future releases.
Summary:
- Refactor the buffer cache to use bulk page allocation
- Convert agnumber-based AG iteration to walk per-AG structures
- Clean up some unit conversions and other code warts
- Reduce spinlock contention in the directio fastpath
- Collapse all the inode cache walks into a single function
- Remove indirect function calls from the inode cache walk code
- Dramatically reduce the number of cache flushes sent when writing log buffers
- Preserve inode sickness reports for longer
- Rename xfs_eofblocks since it controls inode cache walks
- Refactor the extended attribute code to prepare it for the addition of log intent items to make xattrs fully transactional
- A few fixes to earlier large patchsets
- Log recovery fixes so that we don't accidentally mark the log clean when log intent recovery fails
- Fix some latent SOB errors
- Clean up shutdown messages that get logged to dmesg
- Fix a regression in the online shrink code
- Fix a UAF in the buffer logging code if the fs goes offline
- Fix uninitialized error variables
- Fix a UAF in the CIL when commited log item callbacks race with a shutdown
- Fix a bug where the CIL could hang trying to push part of the log ring buffer that hasn't been filled yet"

xfs: initial agnumber -> perag conversions for shrink
If we want to use active references to the perag to be able to gate shrink removing AGs and hence perags safely, we've got a fair bit of work to do actually use perags in all the places we need to.
There's a lot of code that iterates ag numbers and then looks up perags from that, often multiple times for the same perag in the one operation. If we want to use reference counted perags for access control, then we need to convert all these uses to perag iterators, not agno iterators.
[Patches 1-4]
The first step of this is consolidating all the perag management - init, free, get, put, etc into a common location. THis is spread all over the place right now, so move it all into libxfs/xfs_ag.[ch]. This does expose kernel only bits of the perag to libxfs and hence userspace, so the structures and code is rearranged to minimise the number of ifdefs that need to be added to the userspace codebase. The perag iterator in xfs_icache.c is promoted to a first class API and expanded to the needs of the code as required.
[Patches 5-10]
These are the first basic perag iterator conversions and changes to pass the perag down the stack from those iterators where appropriate. A lot of this is obvious, simple changes, though in some places we stop passing the perag down the stack because the code enters into an as yet unconverted subsystem that still uses raw AGs.
[Patches 11-16]
These replace the agno passed in the btree cursor for per-ag btree operations with a perag that is passed to the cursor init function. The cursor takes it's own reference to the perag, and the reference is dropped when the cursor is deleted. Hence we get reference coverage for the entire time the cursor is active, even if the code that initialised the cursor drops it's reference before the cursor or any of it's children (duplicates) have been deleted.
The first patch adds the perag infrastructure for the cursor, the next four patches convert a btree cursor at a time, and the last removes the agno from the cursor once it is unused.
[Patches 17-21]
These patches are a demonstration of the simplifications and cleanups that come from plumbing the perag through interfaces that select and then operate on a specific AG. In this case the inode allocation algorithm does up to three walks across all AGs before it either allocates an inode or fails. Two of these walks are purely just to select the AG, and even then it doesn't guarantee inode allocation success so there's a third walk if the selected AG allocation fails.
These patches collapse the selection and allocation into a single loop, simplifies the error handling because xfs_dir_ialloc() always returns ENOSPC if no AG was selected for inode allocation or we fail to allocate an inode in any AG, gets rid of xfs_dir_ialloc() wrapper, converts inode allocation to run entirely from a single perag instance, and then factors xfs_dialloc() into a much, much simpler loop which is easy to understand.
Hence we end up with the same inode allocation logic, but it only needs two complete iterations at worst, makes AG selection and allocation atomic w.r.t. shrink and chops out out over 100 lines of code from this hot code path.
[Patch 22]
Converts the unlink path to pass perags through it.
There's more conversion work to be done, but this patchset gets through a large chunk of it in one hit. Most of the iterators are converted, so once this is solidified we can move on to converting these to active references for being able to free perags while the fs is still active.
