Ok, so EBUSY implies a setup race - multiple filesystems are trying to run the init code at the same time. That seems somewhat unlikely, but regardless what I'm going to do is move this setup/teardown to the XFS module init functions rather than do it in the CIL. i.e. turn this into a generic XFS filesystem hotplug infrastructure in xfs_super.c and call out to xlog_cil_pcp_dead() from there. This way we are guaranteed a single init call when the module is inserted, and a single destroy call when the module is removed. That should solve all these issues. How do you want me to handle these changes? Just send out the replacement patches for the code that is alread in the branch for review, then resend a rebased pull-req after review? Or something else? I don't really want to keep bombing the mailing list with 40 emails every time I need to get fixes for a single patch reviewed... Cheers, Dave.

I've tested the two patches that will appear as replies to this mail as the replacement for the one hotplug infrastructure patch in the original series. I've tested it against modular XFS builds, and it doesn't cause any problems here. Essentially the first patch splits out the XFS hotplug infrastructure, the second is the CIL functionality for handling dead CPU notifications. If they work for you, I'll rebase the branch for you to reconstruct the for-next tree with the fixes in it... Cheers, Dave.

Hi Darrick, Can you please pull the CIL and log improvements from the tag listed below? Cheers, Dave. The following changes since commit d07f6ca923ea0927a1024dfccafc5b53b61cfecc: Linux 5.13-rc2 (2021-05-16 15:27:44 -0700) are available in the Git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/dgc/linux-xfs.git tags/xfs-cil-scale-tag for you to fetch changes up to 856d6346ad5e76f230906792b1eb4ba70c860748: xfs: expanding delayed logging design with background material (2021-06-04 12:42:29 +1000) ---------------------------------------------------------------- xfs: CIL and log scalability improvements Performance improvements are largely documented in the change logs of the individual patches. Headline numbers are an increase in transaction rate from 700k commits/s to 1.7M commits/s, and a reduction in fua/flush operations by 2-3 orders of magnitude on metadata heavy workloads that don't use fsync. Summary of series: Patches Modifications ------- ------------- 1-7: log write FUA/FLUSH optimisations 8: bug fix 9-11: Async CIL pushes 12-25: xlog_write() rework 26-39: CIL commit scalability The log write FUA/FLUSH optimisations reduce the number of cache flushes required to flush the CIL to the journal. It extends the old pre-delayed logging ordering semantics required by writing individual transactions to the iclogs out to cover then CIL checkpoint transactions rather than individual writes to the iclogs. In doing so, we reduce the cache flush requirements to once per CIL checkpoint rather than once per iclog write. The async CIL pushes fix a pipeline limitation that only allowed a single CIL push to be processed at a time. This was causing CIL checkpoint writing to become CPU bound as only a single CIL checkpoint could be pushed at a time. The checkpoint pipleine was designed to allow multiple pushes to be in flight at once and use careful ordering of the commit records to ensure correct recovery order, but the workqueue implementation didn't allow concurrent works to be run. The concurrent works now extend out to 4 CIL checkpoints running at a time, hence removing the CPU usage limiations without introducing new lock contention issues. The xlog_write() rework is long overdue. The code is complex, difficult to understand, full of tricky, subtle corner cases and just generally really hard to modify. This patchset reworks the xlog_write() API to reduce the processing overhead of writing out long log vector chains, and factors the xlog_write() code into a simple, compact fast path along with a clearer slow path to handle the complex cases. The CIL commit scalability patchset removes spinlocks from the transaction commit fast path. These spinlocks are the performance limiting bottleneck in the transaction commit path, so we apply a variety of different techniques to do either atomic. lockless or per-cpu updates of the CIL tracking structures during commits. This greatly increases the throughput of the the transaction commit engine, moving the contention point to the log space tracking algorithms after doubling throughput on 32-way workloads. ---------------------------------------------------------------- Dave Chinner (39): xfs: log stripe roundoff is a property of the log xfs: separate CIL commit record IO xfs: remove xfs_blkdev_issue_flush xfs: async blkdev cache flush xfs: CIL checkpoint flushes caches unconditionally xfs: remove need_start_rec parameter from xlog_write() xfs: journal IO cache flush reductions xfs: Fix CIL throttle hang when CIL space used going backwards xfs: xfs_log_force_lsn isn't passed a LSN xfs: AIL needs asynchronous CIL forcing xfs: CIL work is serialised, not pipelined xfs: factor out the CIL transaction header building xfs: only CIL pushes require a start record xfs: embed the xlog_op_header in the unmount record xfs: embed the xlog_op_header in the commit record xfs: log tickets don't need log client id xfs: move log iovec alignment to preparation function xfs: reserve space and initialise xlog_op_header in item formatting xfs: log ticket region debug is largely useless xfs: pass lv chain length into xlog_write() xfs: introduce xlog_write_single() xfs:_introduce xlog_write_partial() xfs: xlog_write() no longer needs contwr state xfs: xlog_write() doesn't need optype anymore xfs: CIL context doesn't need to count iovecs xfs: use the CIL space used counter for emptiness checks xfs: lift init CIL reservation out of xc_cil_lock xfs: rework per-iclog header CIL reservation xfs: introduce per-cpu CIL tracking structure xfs: implement percpu cil space used calculation xfs: track CIL ticket reservation in percpu structure xfs: convert CIL busy extents to per-cpu xfs: Add order IDs to log items in CIL xfs: convert CIL to unordered per cpu lists xfs: convert log vector chain to use list heads xfs: move CIL ordering to the logvec chain xfs: avoid cil push lock if possible xfs: xlog_sync() manually adjusts grant head space xfs: expanding delayed logging design with background material Documentation/filesystems/xfs-delayed-logging-design.rst | 361 ++++++++++++++++++++++++++---- fs/xfs/libxfs/xfs_log_format.h | 4 - fs/xfs/libxfs/xfs_types.h | 1 + fs/xfs/xfs_bio_io.c | 35 +++ fs/xfs/xfs_buf.c | 2 +- fs/xfs/xfs_buf_item.c | 39 ++-- fs/xfs/xfs_dquot_item.c | 2 +- fs/xfs/xfs_file.c | 20 +- fs/xfs/xfs_inode.c | 10 +- fs/xfs/xfs_inode_item.c | 18 +- fs/xfs/xfs_inode_item.h | 2 +- fs/xfs/xfs_linux.h | 2 + fs/xfs/xfs_log.c | 1015 +++++++++++++++++++++++++++++++++++++++--------------------------------------------- fs/xfs/xfs_log.h | 66 ++---- fs/xfs/xfs_log_cil.c | 822 ++++++++++++++++++++++++++++++++++++++++++++++++++------------------ fs/xfs/xfs_log_priv.h | 114 +++++----- fs/xfs/xfs_super.c | 13 +- fs/xfs/xfs_super.h | 1 - fs/xfs/xfs_sysfs.c | 1 + fs/xfs/xfs_trace.c | 1 + fs/xfs/xfs_trans.c | 18 +- fs/xfs/xfs_trans.h | 5 +- fs/xfs/xfs_trans_ail.c | 11 +- fs/xfs/xfs_trans_priv.h | 3 +- include/linux/cpuhotplug.h | 1 + 25 files changed, 1603 insertions(+), 964 deletions(-)
