Subject: fscache: Pass the correct cancelled indications to fscache_op_complete()
X-Git-Tag: v4.17-rc1~90^2~7
X-Git-Url: https://asedeno.scripts.mit.edu/gitweb/?a=commitdiff_plain;h=b27ddd46245311850f850024df54d0537506f3c1;p=linux.git

fscache: Pass the correct cancelled indications to fscache_op_complete()

The last parameter to fscache_op_complete() is a bool indicating whether or
not the operation was cancelled.  A lot of the time the inverse value is
given or no differentiation is made.  Fix this.
