Merge tag 'xfs-4.17-merge-1' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux
Pull xfs updates from Darrick Wong: "Here's the first round of fixes for XFS for 4.17. The biggest new features this time around are the addition of lazytime support, further enhancement of the on-disk inode metadata verifiers, and a patch to smooth over some of the AGFL padding problems that have intermittently plagued users since 4.5. I forsee sending a second pull request next week with further bug fixes and speedups in the online scrub code and elsewhere. This series 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. Summary of changes for this release: - Various cleanups and code fixes - Implement lazytime as a mount option - Convert various on-disk metadata checks from asserts to -EFSCORRUPTED - Fix accounting problems with the rmap per-ag reservations - Refactorings and cleanups for xfs_log_force - Various bugfixes for the reflink code - Work around v5 AGFL padding problems to prevent fs shutdowns - Establish inode fork verifiers to inspect on-disk metadata correctness - Various online scrub fixes - Fix v5 swapext blowing up on deleted inodes" * tag 'xfs-4.17-merge-1' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux: (49 commits) xfs: do not log/recover swapext extent owner changes for deleted inodes xfs: clean up xfs_mount allocation and dynamic initializers xfs: remove dead inode version setting code xfs: catch inode allocation state mismatch corruption xfs: xfs_scrub_iallocbt_xref_rmap_inodes should use xref_set_corrupt xfs: flag inode corruption if parent ptr doesn't get us a real inode xfs: don't accept inode buffers with suspicious unlinked chains xfs: move inode extent size hint validation to libxfs xfs: record inode buf errors as a xref error in inobt scrubber xfs: remove xfs_buf parameter from inode scrub methods xfs: inode scrubber shouldn't bother with raw checks xfs: bmap scrubber should do rmap xref with bmap for sparse files xfs: refactor inode buffer verifier error logging xfs: refactor inode verifier error logging xfs: refactor bmap record validation xfs: sanity-check the unused space before trying to use it xfs: detect agfl count corruption and reset agfl xfs: unwind the try_again loop in xfs_log_force xfs: refactor xfs_log_force_lsn xfs: minor cleanup for xfs_reflink_end_cow ...
