Hi Carlos, Please pull this branch with changes for xfs. 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. --D The following changes since commit c2358439af374cad47f771797875d0beb8256738: xfs: enable realtime rmap btree (2024-12-23 13:06:09 -0800) are available in the Git repository at: https://git.kernel.org/pub/scm/linux/kernel/git/djwong/xfs-linux.git tags/realtime-reflink_2024-12-23 for you to fetch changes up to 155debbe7e627baf6439e75f15856d40ec115c5d: xfs: enable realtime reflink (2024-12-23 13:06:17 -0800) ---------------------------------------------------------------- xfs: reflink on the realtime device [v6.2 05/14] This patchset enables use of the file data block sharing feature (i.e. reflink) on the realtime device. It follows the same basic sequence as the realtime rmap series -- first a few cleanups; then introduction of the new btree format and inode fork format. Next comes enabling CoW and remapping for the rt device; new scrub, repair, and health reporting code; and at the end we implement some code to lengthen write requests so that rt extents are always CoWed fully. This has been running on the djcloud for months with no problems. Enjoy! Signed-off-by: "Darrick J. Wong" <djwong@xxxxxxxxxx> ---------------------------------------------------------------- Christoph Hellwig (1): xfs: refactor xfs_reflink_find_shared Darrick J.
