The log covering background task used to be part of the xfssyncd workqueue. That workqueue was removed as of commit 5889608d ("xfs: syncd workqueue is no more") and the associated work item scheduled to the xfs-log wq. The latter is used for log buffer I/O completion. Since xfs_log_worker() can invoke a log flush, a deadlock is possible between the xfs-log and xfs-cil workqueues. Consider the following codepath from xfs_log_worker(): xfs_log_worker() xfs_log_force() _xfs_log_force() xlog_cil_force() xlog_cil_force_lsn() xlog_cil_push_now() flush_work() The above is in xfs-log wq context and blocked waiting on the completion of an xfs-cil work item. Concurrently, the cil push in progress can end up blocked here: xlog_cil_push_work() xlog_cil_push() xlog_write() xlog_state_get_iclog_space() xlog_wait(&log->l_flush_wait, ...) The above is in xfs-cil context waiting on log buffer I/O completion, which executes in xfs-log wq context. In this scenario both workqueues are deadlocked waiting on eachother. Add a new workqueue specifically for the high level log covering and ail pushing worker, as was the case prior to commit 5889608d.

The new helpers don't enforce that [pos,offset) lies strictly on [0,i_size) when being called from xfs_free_file_space(), so by "leaking" these ranges into xfs_zero_range() we get this buggy behavior. Fix this by reintroducing the checks xfs_zero_remaining_bytes() did against i_size at the bottom of xfs_free_file_space().

The inline directory verifiers should be called on the inode fork data, which means after iformat_local on the read side, and prior to ifork_flush on the write side. This makes the fork verifier more consistent with the way buffer verifiers work -- i.e. they will operate on the memory buffer that the code will be reading and writing directly. Furthermore, revise the verifier function to return -EFSCORRUPTED so that we don't flood the logs with corruption messages and assert notices. This has been a particular problem with xfs/348, which triggers the XFS_WANT_CORRUPTED_RETURN assertions, which halts the kernel when CONFIG_XFS_DEBUG=y. Disk corruption isn't supposed to do that, at least not in a verifier. Reviewed-by: NBrian Foster <bfoster@redhat.com> Reviewed-by: NChristoph Hellwig <hch@lst.de> Signed-off-by: NDarrick J.

This workqueue is used by our storage target mode ULPs via the new CQ API. Recent observations when working with very high-end flash storage devices reveal that UNBOUND workqueue threads can migrate between cpu cores and even numa nodes (although some numa locality is accounted for). While this attribute can be useful in some workloads, it does not fit in very nicely with the normal run-to-completion model we usually use in our target-mode ULPs and the block-mq irq<->cpu affinity facilities. The whole block-mq concept is that the completion will land on the same cpu where the submission was performed. The fact that our submitter thread is migrating cpus can break this locality. We assume that as a target mode ULP, we will serve multiple initiators/clients and we can spread the load enough without having to use unbound kworkers. Also, while we're at it, expose this workqueue via sysfs which is harmless and can be useful for debug.

Pull arm64 fixes from Will Deacon: "There's a kaslr fix and then two patches to update our native and compat syscall tables. Arnd asked that we take the addition of statx to the asm-generic unistd.h via arm64, as he didn't have anything queued in the asm-generic tree. Summary: - Fix mapping of kernel image under certain kaslr offsets - Hook up new statx syscall in asm-generic syscall table - Update compat syscall table to match arch/arm/ (pkeys and statx)" * tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux: arm64: kaslr: Fix up the kernel image alignment arm64: compat: Update compat syscalls generic syscalls: Wire up statx syscall

When vmalloc_user is used to create memory that is supposed to be mmap'd to user space, it is necessary for the mmap cookie (eg the offset) to be aligned to SHMLBA. This creates a situation where all virtual mappings of the same physical page share the same virtual cache index and guarantees VIPT coherence. Otherwise the cache is non-coherent and the kernel will not see writes by userspace when reading the shared page (or vice-versa).
