[PATCH 0/7] perf tools: Clarify overwrite and backward, bugfix

From: Wang Nan
Date: Sun Nov 12 2017 - 20:40:39 EST


Based on previous discussion, perf needs to support only two types
of ringbuffer: read-write + forward, readonly + backward. This patchset
completly removes the concept of 'overwrite' from code level, controls
mapping permission using write_backward instead.

Wang Nan (7):
perf mmap: Fix perf backward recording
perf tests: Set evlist of test__backward_ring_buffer() to !overwrite
perf tests: Set evlist of test__sw_clock_freq() to !overwrite
perf tests: Set evlist of test__basic_mmap() to !overwrite
perf tests: Set evlist of test__task_exit() to !overwrite
perf tools: Remove 'overwrite' concept from code level
perf tools: Remove prot field in mmap param
