Subject: - add fs_sink filter method which blocks until the backing filter is synced.
X-Git-Tag: v1_7_110~2^11~207
X-Git-Url: https://git.whamcloud.com/?a=commitdiff_plain;h=3a8efcaf4df65beac15e2ad0c7c6ef7d951c3adb;p=fs%2Flustre-release.git

- add fs_sink filter method which blocks until the backing filter is synced.
  ext* uses ext*_force_commit, reiser is unimplemented
- add /proc/sys/lustre/filter_sync_on_commit tunable, disabled by default.
  when enabled it calls the filter sync after each filter_commitrw for write
