Thank you!
Hi Linus, Please pull this second large pile of new stuff for 5.10, with changes even more monumental than last week! We are formally announcing the deprecation of the V4 filesystem format in 2030. All users must upgrade to the V5 format, which contains design improvements that greatly strengthen metadata validation, supports reflink and online fsck, and is the intended vehicle for handling timestamps past 2038. We're also deprecating the old Irix behavioral tweaks in September 2025. Coming along for the ride are two design changes to the deferred metadata ops subsystem. One of the improvements is to retain correct logical ordering of tasks and subtasks, which is a more logical design for upper layers of XFS and will become necessary when we add atomic file range swaps and commits. The second improvement to deferred ops improves the scalability of the log by helping the log tail to move forward during long-running operations. This reduces log contention when there are a large number of threads trying to run transactions. In addition to that, this pull request fixes numerous small bugs in log recovery; refactors logical intent log item recovery to remove the last remaining place in XFS where we could have nested transactions; fixes a couple of ways that intent log item recovery could fail in ways that wouldn't have happened in the regular commit paths; fixes a deadlock vector in the GETFSMAP implementation (which improves its performance by 20%); and fixes serious bugs in the realtime growfs, fallocate, and bitmap handling code. I anticipate sending a third pull request in a few days with bug fixes, but otherwise that's it for XFS for 5.10. :) The branch merges cleanly with upstream as of a few minutes ago, so please let me know if anything strange happens. --D The following changes since commit fe341eb151ec0ba80fb74edd6201fc78e5232b6b: xfs: ensure that fpunch, fcollapse, and finsert operations are aligned to rt extent size (2020-09-15 20:52:42 -0700) are available in the Git repository at: git://git.kernel.org/pub/scm/fs/xfs/xfs-linux.git tags/xfs-5.10-merge-5 for you to fetch changes up to 894645546bb12ce008dcba0f68834d270fcd1dde: xfs: fix Kconfig asking about XFS_SUPPORT_V4 when XFS_FS=n (2020-10-16 15:34:28 -0700) ---------------------------------------------------------------- Recalling the first round of new code for 5.10, in which we added: - New feature: Widen inode timestamps and quota grace expiration timestamps to support dates through the year 2486. - New feature: storing inode btree counts in the AGI to speed up certain mount time per-AG block reservation operatoins and add a little more metadata redundancy. For the second round of new code for 5.10: - Deprecate the V4 filesystem format, some disused mount options, and some legacy sysctl knobs now that we can support dates into the 25th century. Note that removal of V4 support will not happen until the early 2030s. - Fix some probles with inode realtime flag propagation. - Fix some buffer handling issues when growing a rt filesystem. - Fix a problem where a BMAP_REMAP unmap call would free rt extents even though the purpose of BMAP_REMAP is to avoid freeing the blocks. - Strengthen the dabtree online scrubber to check hash values on child dabtree blocks. - Actually log new intent items created as part of recovering log intent items. - Fix a bug where quotas weren't attached to an inode undergoing bmap intent item recovery. - Fix a buffer overrun problem with specially crafted log buffer headers. - Various cleanups to type usage and slightly inaccurate comments. - More cleanups to the xattr, log, and quota code. - Don't run the (slower) shared-rmap operations on attr fork mappings. - Fix a bug where we failed to check the LSN of finobt blocks during replay and could therefore overwrite newer data with older data. - Clean up the ugly nested transaction mess that log recovery uses to stage intent item recovery in the correct order by creating a proper data structure to capture recovered chains. - Use the capture structure to resume intent item chains with the same log space and block reservations as when they were captured. - Fix a UAF bug in bmap intent item recovery where we failed to maintain our reference to the incore inode if the bmap operation needed to relog itself to continue. - Rearrange the defer ops mechanism to finish newly created subtasks of a parent task before moving on to the next parent task. - Automatically relog intent items in deferred ops chains if doing so would help us avoid pinning the log tail. This will help fix some log scaling problems now and will facilitate atomic file updates later. - Fix a deadlock in the GETFSMAP implementation by using an internal memory buffer to reduce indirect calls and copies to userspace, thereby improving its performance by ~20%. - Fix various problems when calling growfs on a realtime volume would not fully update the filesystem metadata. - Fix broken Kconfig asking about deprecated XFS when XFS is disabled. ---------------------------------------------------------------- Brian Foster (1): xfs: drop extra transaction roll from inode extent truncate Chandan Babu R (2): xfs: Set xfs_buf type flag when growing summary/bitmap files xfs: Set xfs_buf's b_ops member when zeroing bitmap/summary files Darrick J.
