Hi Andrey, Please pull this branch with changes for xfsprogs for 6.14-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 d3fc26fa2ac96c39836884525065f5d47dda8b05: mkfs: create the realtime rmap inode (2025-02-25 09:16:01 -0800) are available in the Git repository at: https://git.kernel.org/pub/scm/linux/kernel/git/djwong/xfsprogs-dev.git tags/realtime-reflink-6.14_2025-02-25 for you to fetch changes up to 17408f8871e100b2987174b6cf480ee68e44e1a3: mkfs: enable reflink on the realtime device (2025-02-25 09:16:02 -0800) ---------------------------------------------------------------- xfsprogs: reflink on the realtime device [v6.6 5/7] 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.
