[PATCH V2 5/8] perf mmap: Using stored 'overwrite' in perf_mmap__consume

From: kan . liang
Date: Tue Mar 06 2018 - 10:38:53 EST


From: Kan Liang <kan.liang@xxxxxxxxxxxxxxx>

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.
