Hi Chandan, Please pull this branch with changes for xfs for 6.9-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. --D The following changes since commit a1f3e0cca41036c3c66abb6a2ed8fedc214e9a4c: xfs: update health status if we get a clean bill of health (2024-02-22 12:33:04 -0800) are available in the Git repository at: https://git.kernel.org/pub/scm/linux/kernel/git/djwong/xfs-linux.git tags/repair-fscounters-6.9_2024-02-23 for you to fetch changes up to 4ed080cd7cb077bbb4b64f0712be1618c9d55a0d: xfs: repair summary counters (2024-02-22 12:33:05 -0800) ---------------------------------------------------------------- xfs: online repair for fs summary counters [v29.3 06/18] A longstanding deficiency in the online fs summary counter scrubbing code is that it hasn't any means to quiesce the incore percpu counters while it's running. There is no way to coordinate with other threads are reserving or freeing free space simultaneously, which leads to false error reports. Right now, if the discrepancy is large, we just sort of shrug and bail out with an incomplete flag, but this is lame. For repair activity, we actually /do/ need to stabilize the counters to get an accurate reading and install it in the percpu counter. To improve the former and enable the latter, allow the fscounters online fsck code to perform an exclusive mini-freeze on the filesystem. The exclusivity prevents userspace from thawing while we're running, and the mini-freeze means that we don't wait for the log to quiesce, which will make both speedier. This has been running on the djcloud for months with no problems. Enjoy! Signed-off-by: Darrick J. Wong <djwong@xxxxxxxxxx> ---------------------------------------------------------------- Darrick J.
