Subject: [PATCH v8 0/2] improve sync efficiency with sb inode wb list
Date: Wed, 22 Jun 2016 07:23:11 -0400 [thread overview]
Message-ID: <1466594593-6757-1-git-send-email-bfoster@redhat.com> (raw)
This is just a rebase to linus' latest master. I haven't heard any
feedback on this one so Jan suggested I send to a wider audience.
Brian
v8:
- Rebased to latest master.
- Added Holger's Tested-by.
v7: http://marc.info/?l=linux-fsdevel&m=145349651407631&w=2
- Updated patch 1/2 commit log description to reference performance
impact.
v6: http://marc.info/?l=linux-fsdevel&m=145322635828644&w=2
- Use rcu locking instead of s_inode_list_lock spinlock in
wait_sb_inodes().
- Refactor wait_sb_inodes() to keep inode on wb list.
- Drop remaining, unnecessary lazy list removal bits and relocate inode
list check to clear_inode().
- Fix up some comments, etc.
v5: http://marc.info/?l=linux-fsdevel&m=145262374402798&w=2
- Converted from per-bdi list to per-sb list. Also marked as RFC and
dropped testing/review tags.
- Updated to use new irq-safe lock for wb list.
- Dropped lazy list removal. Inodes are removed when the mapping is
cleared of the writeback tag.
- Tweaked wait_sb_inodes() to remove deferred iput(), other cleanups.
- Added wb list tracepoint patch.
v4: http://marc.info/?l=linux-fsdevel&m=143511628828000&w=2
