From 6e3647acb4f200add1d8e0203514f7ac925ae463 Mon Sep 17 00:00:00 2001 From: Frederic Weisbecker Date: Fri, 1 May 2009 02:27:39 +0200 Subject: 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.
