Hi Andrey, Please pull this branch with changes for xfsprogs for 6.11-rc1. As usual, I did a test-merge with the main upstream branch as of a few minutes ago, and didn't see any conflicts. Please let me know if you encounter any problems. The following changes since commit 6611215e3d441a5e6d9d6a2f85c5ea1bf573a8d0: xfs: update the pag for the last AG at recovery time (2024-10-31 15:45:04 -0700) are available in the Git repository at: https://git.kernel.org/pub/scm/linux/kernel/git/djwong/xfsprogs-dev.git tags/atomic-file-commits-6.12_2024-10-31 for you to fetch changes up to 1cf7afbc0c8bcb450ebc3acab7616c9da49087de: xfs_io: add atomic file update commands to exercise file commit range (2024-10-31 15:45:04 -0700) ---------------------------------------------------------------- xfsprogs: atomic file content commits [v31.3 2/7] This series creates XFS_IOC_START_COMMIT and XFS_IOC_COMMIT_RANGE ioctls to perform the exchange only if the target file has not been changed since a given sampling point. This new functionality uses the mechanism underlying EXCHANGE_RANGE to stage and commit file updates such that reader programs will see either the old contents or the new contents in their entirety, with no chance of torn writes. A successful call completion guarantees that the new contents will be seen even if the system fails. The pair of ioctls allows userspace to perform what amounts to a compare and exchange operation on entire file contents. Note that there are ongoing arguments in the community about how best to implement some sort of file data write counter that nfsd could also use to signal invalidations to clients. Until such a thing is implemented, this patch will rely on ctime/mtime updates. Signed-off-by: Darrick J.
