Hi all, This series tweaks the xfs_log_quiesce() codepath to lift out the explicit buffer target LRU draining and isolate it to the unmount path. It's unnecessary to reclaim all buffers on filesystem freeze or read-only remount, and this also causes such operations to stall if a read heavy workload is running in parallel. Patch 1 is a simple rename and patch 2 implements the functional change. Thoughts, reviews, flames appreciated.
