kill-the-BKL/reiserfs: release the write lock on flush_commit_list()
flush_commit_list() uses ll_rw_block() to commit the pending log blocks. ll_rw_block() might sleep, and the bkl was released at this point. Then we can also relax the write lock at this point. [ Impact: release the reiserfs write lock when it is not needed ] Cc: Jeff Mahoney <jeffm@suse.com> Cc: Chris Mason <chris.mason@oracle.com> Cc: Alexander Beregalov <a.beregalov@gmail.com> Signed-off-by: Frederic Weisbecker <fweisbec@gmail.com>
