X-Git-Tag: v3.2.62~56
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=38f8813cf29676b719ad3f15ae9489ce95b98ea9;p=thirdparty%2Fkernel%2Fstable.git

fuse: timeout comparison fix

commit 126b9d4365b110c157bc4cbc32540dfa66c9c85a upstream.

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