Subject: [PATCH 0/8] Per-bdi writeback flusher threads v18
Hi,
This is the 18th release of the writeback patchset. Changes since
v17 include:
- Change the naming of sync_sb_inodes() and sync_sb_inodes_wait(). It's
now writeback_inodes_sb() to start writeback on dirty sb inodes, and
sync_inodes_sb() to start and wait on writeback. Suggestion from Jan
Kara, and I agree it better explains what the code does.
- Fix compile error in pohmelfs.
- Update Ted's MAX_WRITEBACK_PAGES patch to be MB based instead of in
pages.
- Integrate the suggestions from Christoph:
- Move wakeup_flusher_threads() into fs/fs-writeback.c, it fits
better there and allows us to make bdi_writeback_all() static.
- Get rid of generic_sync_sb_inodes(). Move the issue and wait
into the two callers instead, making the old function now
wait_sb_inodes() and only concerned with waiting on already
issued IO.
- wbc->nr_to_write was mistakenly set to LLONG_MAX instead of
LONG_MAX.
Please review, thanks!
