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 c89b1f70b43dc7d1dd7147d5147170db651131a4: xfs: fix the entry condition of exact EOF block allocation optimization (2025-02-25 09:16:00 -0800) are available in the Git repository at: https://git.kernel.org/pub/scm/linux/kernel/git/djwong/xfsprogs-dev.git tags/realtime-rmap-6.14_2025-02-25 for you to fetch changes up to d3fc26fa2ac96c39836884525065f5d47dda8b05: mkfs: create the realtime rmap inode (2025-02-25 09:16:01 -0800) ---------------------------------------------------------------- xfsprogs: realtime reverse-mapping support [v6.6 4/7] This is the latest revision of a patchset that adds to XFS kernel support for reverse mapping for the realtime device. This time around I've fixed some of the bitrot that I've noticed over the past few months, and most notably have converted rtrmapbt to use the metadata inode directory feature instead of burning more space in the superblock. At the beginning of the set are patches to implement storing B+tree leaves in an inode root, since the realtime rmapbt is rooted in an inode, unlike the regular rmapbt which is rooted in an AG block. Prior to this, the only btree that could be rooted in the inode fork was the block mapping btree; if all the extent records fit in the inode, format would be switched from 'btree' to 'extents'. The next few patches enhance the reverse mapping routines to handle the parts that are specific to rtgroups -- adding the new btree type, adding a new log intent item type, and wiring up the metadata directory tree entries. Finally, implement GETFSMAP with the rtrmapbt and scrub functionality for the rtrmapbt and rtbitmap and online fsck functionality. Signed-off-by: "Darrick J.
