Hi Zorro, Please pull this branch with changes for fstests. 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 915630e294582b91658e300b2302129d77f36504: fstests: test mkfs.xfs protofiles with xattr support (2025-02-20 13:52:18 -0800) are available in the Git repository at: https://git.kernel.org/pub/scm/linux/kernel/git/djwong/xfstests-dev.git tags/realtime-groups_2025-02-20 for you to fetch changes up to 153e2550b7bf4b0ebb3c6d0e1757a6709858a0b0: xfs: fix fuzz tests of rtgroups bitmap and summary files (2025-02-20 13:52:19 -0800) ---------------------------------------------------------------- fstests: shard the realtime section [v6.5 05/22] Right now, the realtime section uses a single pair of metadata inodes to store the free space information. This presents a scalability problem since every thread trying to allocate or free rt extents have to lock these files. It would be very useful if we could begin to tackle these problems by sharding the realtime section, so create the notion of realtime groups, which are similar to allocation groups on the data section. While we're at it, define a superblock to be stamped into the start of each rt section. This enables utilities such as blkid to identify block devices containing realtime sections, and helpfully avoids the situation where a file extent can cross an rtgroup boundary. The best advantage for rtgroups will become evident later when we get to adding rmap and reflink to the realtime volume, since the geometry constraints are the same for rt groups and AGs. Hence we can reuse all that code directly. This has been running on the djcloud for months with no problems. Enjoy! Signed-off-by: "Darrick J.
