Subject: [PATCH 3.12 17/94] fuse: timeout comparison fix

From: Miklos Szeredi <mszeredi@...e.cz>

3.12-stable review patch.  If anyone has any objections, please let me know.

===============

commit 126b9d4365b110c157bc4cbc32540dfa66c9c85a upstream.

As suggested by checkpatch.pl, use time_before64() instead of direct
comparison of jiffies64 values.
