Subject[PATCH 26/54] perf mmap: Use stored 'overwrite' in perf_mmap__consume()
Date
From: Kan Liang <kan.liang@linux.intel.com>

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.
