I'm not against improving the efficiency, but I think it still makes sense to have an option to disable it completely. Since mbcache is already a per-sb cache, having a per-sb mount option makes sense and doesn't interfere with other improvements to mbcache. -- You are receiving this mail because: You are watching the assignee of the bug.
