X-Git-Tag: v4.19~1357^2~31^2~28
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=bdec8b2f7eed4f16b764ca258487d26f8079f5ff;p=platform%2Fkernel%2Flinux-rpi.git

perf mmap: Use stored 'overwrite' in perf_mmap__consume()

The 'overwrite' is set at allocation. It will not be changed.  Using it
to replace the parameter of perf_mmap__consume().  The parameters will
be discarded later.

No functional change.
