[PATCH 4/8] fs/ext3/inode.c: drop if around WARN_ON

From: Julia Lawall
Date: Sat Nov 03 2012 - 16:32:18 EST


From: Julia Lawall <Julia.Lawall@xxxxxxx>

Just use WARN_ON rather than an if containing only WARN_ON(1).

A simplified version of the semantic patch that makes this transformation
is as follows: (http://coccinelle.lip6.fr/)

// <smpl>
@@
expression e;
@@
- if (e) WARN_ON(1);
+ WARN_ON(e);
// </smpl>
