Merge tag 'xfs-4.16-merge-4' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux
Pull xfs updates from Darrick Wong: "This merge cycle, we're again some substantive changes to XFS. Metadata verifiers have been restructured to provide more detail about which part of a metadata structure failed checks, and we've enhanced the new online fsck feature to cross-reference extent allocation information with the other metadata structures. With this pull, the metadata verification part of online fsck is more or less finished, though the feature is still experimental and still disabled by default. We're also preparing to remove the EXPERIMENTAL tag from a couple of features this cycle. This week we're committing a bunch of space accounting fixes for reflink and removing the EXPERIMENTAL tag from reflink; I anticipate that we'll be ready to do the same for the reverse mapping feature next week. (I don't have any pending fixes for rmap; however I wish to remove the tags one at a time.) This giant pile of patches has been run through a full xfstests run over the weekend and through a quick xfstests run against this morning's master, with no major failures reported. Let me know if there's any merge problems -- git merge reported that one of our patches touched the same function as the i_version series, but it resolved things cleanly. Summary: - Log faulting code locations when verifiers fail, for improved diagnosis of corrupt filesystems. - Implement metadata verifiers for local format inode fork data. - Online scrub now cross-references metadata records with other metadata. - Refactor the fs geometry ioctl generation functions. - Harden various metadata verifiers. - Fix various accounting problems. - Fix uncancelled transactions leaking when xattr functions fail. - Prevent the copy-on-write speculative preallocation garbage collector from racing with writeback. - Emit log reservation type information as trace data so that we can compare against xfsprogs. - Fix some erroneous asserts in the online scrub code. - Clean up the transaction reservation calculations. - Fix various minor bugs in online scrub. - Log complaints about mixed dio/buffered writes once per day and less noisily than before. - Refactor buffer log item lists to use list_head. - Break PNFS leases before reflinking blocks. - Reduce lock contention on reflink source files. - Fix some quota accounting problems with reflink. - Fix a serious corruption problem in the direct cow write code where we fed bad iomaps to the vfs iomap consumers. - Various other refactorings. - Remove EXPERIMENTAL tag from reflink!" * tag 'xfs-4.16-merge-4' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux: (94 commits) xfs: remove experimental tag for reflinks xfs: don't screw up direct writes when freesp is fragmented xfs: check reflink allocation mappings iomap: warn on zero-length mappings xfs: treat CoW fork operations as delalloc for quota accounting xfs: only grab shared inode locks for source file during reflink xfs: allow xfs_lock_two_inodes to take different EXCL/SHARED modes xfs: reflink should break pnfs leases before sharing blocks xfs: don't clobber inobt/finobt cursors when xref with rmap xfs: skip CoW writes past EOF when writeback races with truncate xfs: preserve i_rdev when recycling a reclaimable inode xfs: refactor accounting updates out of xfs_bmap_btalloc xfs: refactor inode verifier corruption error printing xfs: make tracepoint inode number format consistent xfs: always zero di_flags2 when we free the inode xfs: call xfs_qm_dqattach before performing reflink operations xfs: bmap code cleanup Use list_head infra-structure for buffer's log items list Split buffer's b_fspriv field Get rid of xfs_buf_log_item_t typedef ...
