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.

Yeah. Brian is sending these patches for a few months and they get ignored.
Andrew, can you please pick them up if Al doesn't? Thanks!

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.
