Hi folks, These are the fixes and cleanups that are part of the non-blocking inode reclaim series I've (slowly) been working on. These fixes and cleanups stand alone, many have already been reviewed, and getting them out of the non-blocking reclaim patchset makes that a much smaller and easier to digest set of patches. The changes in this patchset are for: - limiting the size of checkpoints that the CIL builds to reduce the memory it pins and the latency of commits. - cleaning up the AIL item removal code so we can reduce the number of tail LSN updates to prevent unnecessary thundering herd wakeups - account for reclaimable slab caches in XFS correctly - account for reclaimed pages from buffers correctly - avoiding log IO priority inversions - factoring the inode cluster deletion code to make it more readable and easier to modify for the non-blocking inode reclaim mods. Thoughts, comments and improvemnts welcome. -Dave.
