From c259ae52e204d42f8b2d484c85517a4c367030e1 Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Mon, 21 Jul 2008 09:59:15 +0200 Subject: [PATCH] [PATCH] ocfs2: Release mutex in error handling code The mutex is released on a successful return, so it would seem that it should be released on an error return as well. The semantic patch finds this problem is as follows: (http://www.emn.fr/x-info/coccinelle/) // @@ expression l; @@ mutex_lock(l); ... when != mutex_unlock(l) when any when strict ( if (...) { ... when != mutex_unlock(l) + mutex_unlock(l); return ...; } | mutex_unlock(l); ) // Signed-off-by: Julia Lawall Signed-off-by: Mark Fasheh --- fs/ocfs2/file.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/fs/ocfs2/file.c b/fs/ocfs2/file.c index be2dd95d3a..ec2ed15c3d 100644 --- a/fs/ocfs2/file.c +++ b/fs/ocfs2/file.c @@ -1766,8 +1766,8 @@ out_inode_unlock: out_rw_unlock: ocfs2_rw_unlock(inode, 1); - mutex_unlock(&inode->i_mutex); out: + mutex_unlock(&inode->i_mutex); return ret; } -- 2.39.5
