| H A D | writeback.h | diff 9a46b04f16a032c26bbf0ece61d6cd1e7ba9f627 Tue Jul 26 17:21:53 CDT 2016 Brian Foster <bfoster@redhat.com> fs/fs-writeback.c: inode writeback list tracking tracepoints
The per-sb inode writeback list tracks inodes currently under writeback
to facilitate efficient sync processing. In particular, it ensures that
sync only needs to walk through a list of inodes that were cleaned by
the sync.
Add a couple tracepoints to help identify when inodes are added/removed
to and from the writeback lists. Piggyback off of the writeback
lazytime tracepoint template as it already tracks the relevant inode
information.
