Message-Id: <1348647948-3219-27-git-send-email-swhiteho@redhat.com> Date: Wed, 26 Sep 2012 09:25:47 +0100 From: Steven Whitehouse <swhiteho@...hat.com> To: linux-kernel@...r.kernel.org, cluster-devel@...hat.com Cc: Eric Sandeen <sandeen@...hat.com>, Steven Whitehouse <swhiteho@...hat.com> Subject: [PATCH 26/27] GFS2: fix s_writers.counter imbalance in gfs2_ail_empty_gl From: Eric Sandeen <sandeen@...hat.com> gfs2_ail_empty_gl() contains an "inline version" of gfs2_trans_begin(), so it needs an explicit sb_start_intwrite() as well, to balance the sb_end_intwrite() which will be called by gfs2_trans_end(). With this, xfstest 068 passes on lock_nolock local gfs2. Without it, we reach a writer count of -1 and get stuck.
