Pull xfs updates from Darrick Wong: "There's a lot going on this cycle with cleanups in the log code, the btree code, and the xattr code. We're tightening of metadata validation and online fsck checking, and introducing a common btree rebuilding library so that we can refactor xfs_repair and introduce online repair in a future cycle. We also fixed a few visible bugs -- most notably there's one in getdents that we introduced in 5.6; and a fix for hangs when disabling quotas. This series has been running fstests & other QA in the background for over a week and looks good so far. I anticipate sending a second pull request next week. That batch will change how xfs interacts with memory reclaim; how the log batches and throttles log items; how hard writes near ENOSPC will try to squeeze more space out of the filesystem; and hopefully fix the last of the umount hangs after a catastrophic failure. That should ease a lot of problems when running at the limits, but for now I'm leaving that in for-next for another week to make sure we got all the subtleties right. Summary: - Fix a hard to trigger race between iclog error checking and log shutdown. - Strengthen the AGF verifier. - Ratelimit some of the more spammy error messages. - Remove the icdinode uid/gid members and just use the ones in the vfs inode. - Hold ILOCK across insert/collapse range. - Clean up the extended attribute interfaces. - Clean up the attr flags mess. - Restore PF_MEMALLOC after exiting xfsaild thread to avoid triggering warnings in the process accounting code. - Remove the flexibly-sized array from struct xfs_agfl to eliminate compiler warnings about unaligned pointers and packed structures. - Various macro and typedef removals. - Stale metadata buffers if we decide they're corrupt outside of a verifier. - Check directory data/block/free block owners. - Fix a UAF when aborting inactivation of a corrupt xattr fork. - Teach online scrub to report failed directory and attr name lookups as a metadata corruption instead of a runtime error. - Avoid potential buffer overflows in sysfs files by using scnprintf. - Fix a regression in getdents lookups due to a mistake in pointer arithmetic. - Refactor btree cursor private data structures to use anonymous unions. - Cleanups in the log unmounting code. - Fix a potential mishandling of ENOMEM errors on multi-block directory buffer lookups. - Fix an incorrect test in the block allocation code. - Cleanups and name prefix shortening in the scrub code. - Introduce btree bulk loading code for online repair and scrub. - Fix a quotaoff log item leak (and hang) when the fs goes down midway through a quotaoff operation. - Remove di_version from the incore inode. - Refactor some of the log shutdown checking code. - Record the forcing of the log unmount records in the log force counters. - Fix a longstanding bug where quotacheck would purge the administrator's default quota grace interval and warning limits. - Reduce memory usage when scrubbing directory and xattr trees. - Don't let fsfreeze race with GETFSMAP or online scrub. - Handle bio_add_page failures more gracefully in xlog_write_iclog" * tag 'xfs-5.7-merge-8' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux: (108 commits) xfs: prohibit fs freezing when using empty transactions xfs: shutdown on failure to add page to log bio xfs: directory bestfree check should release buffers xfs: drop all altpath buffers at the end of the sibling check xfs: preserve default grace interval during quotacheck xfs: remove xlog_state_want_sync xfs: move the ioerror check out of xlog_state_clean_iclog xfs: refactor xlog_state_clean_iclog xfs: remove the aborted parameter to xlog_state_done_syncing xfs: simplify log shutdown checking in xfs_log_release_iclog xfs: simplify the xfs_log_release_iclog calling convention xfs: factor out a xlog_wait_on_iclog helper xfs: merge xlog_cil_push into xlog_cil_push_work xfs: remove the di_version field from struct icdinode xfs: simplify a check in xfs_ioctl_setattr_check_cowextsize xfs: simplify di_flags2 inheritance in xfs_ialloc xfs: only check the superblock version for dinode size calculation xfs: add a new xfs_sb_version_has_v3inode helper xfs: fix unmount hang and memory leak on shutdown during quotaoff xfs: factor out quotaoff intent AIL removal and memory free ...
