Subject[RFC PATCH v2 0/7] libperf: Add interface for overflow check of sampling events
Date
This patch series adds interface for overflow check of sampling events
to libperf.

First patch fixes a typo in the error message that I noticed.

Second patch move 'open_flags' from tools/perf to evsel::open_flags.

Third patch adds a interface to perform IOC_REFRESH and IOC_PERIOD.

Fourth patch introduce perf_{evsel, evlist}__open_opt() with extensible
structure opts.

Fifth patch adds a interface to check overflowed events.

Sixth and seventh patch adds tests.
