Subject: [RFC PATCH 0/7] libperf: Add overflow detection of sampling events

From: Shunsuke Nakamura <nakamura.shun@...itsu.com>

This patch series adds sampling event overflow detection capability
to libperf.

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

Second patch  adds a interface to set PERF_FLAG_FD_CLOEXEC

Third patch adds a interface to perform IOC_REFRESH and IOC_PERIOD.

Fourth patch adds a interface to set the signal handler.

Fifth patch adds a interface to detect overflowed events.

Sixth and seventh patch adds tests.

Shunsuke Nakamura (7):
  libperf tests: Fix typo in the error message "evsel" -> "evlist"
  libperf: Add perf_evsel__set_close_on_exec() function
  libperf: Add perf_evsel__refresh()/period() functions
  libperf: Add perf_evsel__set_signal() functions
  libperf: Add perf_evsel__check_fd() functions
  libperf test: Add test_stat_overflow()
  libperf test: Add test_detect_overflow_event()
