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" #
