I only have a nitpick on the patch 6, but otherwise

[PATCH v2 0/8] perf tools: perf tools: Clarify overwrite and backward, bugfix

2017-12-02 Thread Wang Nan
THe final result of this patchset is removing the concept of
'forward/backward', merge them into the concept of 'overwrite'.

Patch 1 to 5 clear arguments lists of many functions, remove the
'overwrite'. Because all callers of these functions doesn't need
the overwrite be set, we can simply remove them from arguments
lists and adjust code as if a 'false' is given.

Patch 6 fix a bug that forget to setting readonly for overwrite
ring buffers.

Patch 7 is suggested by Liang Kan, prevent dumpping duplicated
data if there's no so many events between two dumpping commands.

Patch 8 is 's/backward/overwrite'. After patch 8, the concept of
'backward' is removed from most of the code, make it uniform with
user interface ('--overwrite').
