Subject: [RFC/PATCH 7/8] fs/jbd2/journal.c: Use strreplace
Date: Thu,  4 Jun 2015 11:37:14 +0200	[thread overview]
Message-ID: <1433410636-26812-8-git-send-email-linux@rasmusvillemoes.dk> (raw)
In-Reply-To: <1433410636-26812-1-git-send-email-linux@rasmusvillemoes.dk>

In one case, we eliminate a local variable; in the other a strlen()
call and some .text.
