From 78c931b8be75456562b55ed4e27878f1519e1367 Mon Sep 17 00:00:00 2001 From: Brian Foster Date: Fri, 28 Nov 2014 13:59:58 +1100 Subject: xfs: replace global xfslogd wq with per-mount wq The xfslogd workqueue is a global, single-job workqueue for buffer ioend processing. This means we allow for a single work item at a time for all possible XFS mounts on a system. fsstress testing in loopback XFS over XFS configurations has reproduced xfslogd deadlocks due to the single threaded nature of the queue and dependencies introduced between the separate XFS instances by online discard (-o discard). Discard over a loopback device converts the discard request to a hole punch (fallocate) on the underlying file. Online discard requests are issued synchronously and from xfslogd context in XFS, hence the xfslogd workqueue is blocked in the upper fs waiting on a hole punch request to be servied in the lower fs. If the lower fs issues I/O that depends on xfslogd to complete, both filesystems end up hung indefinitely. This is reproduced reliabily by generic/013 on XFS->loop->XFS test devices with the '-o discard' mount option. Further, docker implementations appear to use this kind of configuration for container instance filesystems by default (container fs->dm-> loop->base fs) and therefore are subject to this deadlock when running on XFS. Replace the global xfslogd workqueue with a per-mount variant. This guarantees each mount access to a single worker and prevents deadlocks due to inter-fs dependencies introduced by discard. Since the queue is only responsible for buffer iodone processing at this point in time, rename xfslogd to xfs-buf.

This includes metadata buffer completion and log buffer completion. The log buffer completion requires a high priority queue to prevent stalls due to log forces getting stuck behind other queued work. Rather than continue to prioritize all buffer I/O completion due to the needs of log completion, split log buffer completion off to m_log_workqueue and move the high priority flag from m_buf_workqueue to m_log_workqueue. Add a b_ioend_wq wq pointer to xfs_buf to allow completion workqueue customization on a per-buffer basis. Initialize b_ioend_wq to m_buf_workqueue by default in the generic buffer I/O submission path. Finally, override the default wq with the high priority m_log_workqueue in the log buffer I/O submission path.
