code\") introduced a\nbug to generic code which had been extant for a long time in the XFS\nversion -- it started to call through into lookup_one_len() and hence\ninto the file systems\u0027 -\u003elookup() methods without i_mutex held on the\ndirectory.\n\nThis patch fixes it by locking the directory\u0027s i_mutex again before\ncalling the filldir functions. The original deadlocks which commit\n14f7dd63 was designed to avoid are still avoided, because they were due\nto fs-internal locking, not i_mutex.\n\nWhile we\u0027re at it, fix the return type of nfsd_buffered_readdir() which\nshould be a __be32 not an int -- it\u0027s an NFS errno, not a Linux errno.\nAnd return nfserrno(-ENOMEM) when allocation fails, not just -ENOMEM.\nSparse would have caught that, if it wasn\u0027t so busy bitching about\n__cold__.\n\nCommit 05f4f678 (\"nfsd4: don\u0027t do lookup within readdir in recovery\ncode\") introduced a similar problem with calling lookup_one_len()\nwithout i_mutex, which this patch also addresses. To fix that, it was\nnecessary to fix the called functions so that they expect i_mutex to be\nheld; that part was done by J.

But, the checksumming helper threads prevent it\nfrom being fully effective.\n\nThere are two problems. First, a big queue of pending checksumming\nwill delay the synchronous IO behind other lower priority writes. Second,\nthe checksumming uses an ordered async work queue. The ordering makes sure\nthat IOs are sent to the block layer in the same order they are sent\nto the checksumming threads. Usually this gives us less seeky IO.\n\nBut, when we start mixing IO priorities, the lower priority IO can delay\nthe higher priority IO.\n\nThis patch solves both problems by adding a high priority list to the async\nhelper threads, and a new btrfs_set_work_high_prio(), which is used\nto make put a new async work item onto the higher priority list.\n\nThe ordering is still done on high priority IO, but all of the high\npriority bios are ordered separately from the low priority bios.

acquire\na lock that a driver might try to acquire in its -\u003eremove, in general\nwe should never attempt to flush a workqueue from within the same\nworkqueue, and lockdep rightly complains.\n\nSo as long as sysfs attributes cannot commit suicide directly and we\nare stuck with this callback mechanism, put the sysfs callbacks on\ntheir own workqueue instead of the global one.\n\nThis has the side benefit that if a suicidal sysfs attribute kicks\noff a long chain of -\u003eremove callbacks, we no longer induce a long\ndelay on the global queue.\n\nThis also fixes a missing module_put in the error path introduced\nby sysfs-only-allow-one-scheduled-removal-callback-per-kobj.patch.\n\nWe never destroy the workqueue, but I\u0027m not sure that\u0027s a\nproblem.\n\nReported-by: Kenji
