Subject: kill-the-BKL/reiserfs: release the write lock on flush_commit_list()
X-Git-Tag: v2.6.33-rc1~360^2~20
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=6e3647acb4f200add1d8e0203514f7ac925ae463;p=pandora-kernel.git

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 ]
