From: Steven Rostedt Date: Fri, 6 Mar 2009 02:44:55 +0000 (-0500) Subject: tracing: make all file_operations const X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=5e2336a0d47c9661a40cc5ef85135ce1406af6e8;p=linux-2.6-omap-h63xx.git tracing: make all file_operations const Impact: cleanup All file_operations structures should be constant. No one is going to change them.
