Subject: [PATCH v12 03/15] tools/libperf: avoid counting of nonfilterable fdarray fds
Date: Fri, 17 Jul 2020 10:00:15 +0300	[thread overview]
Message-ID: <b5ab0d2c-b742-0032-e8d3-c8e2eb423c42@linux.intel.com> (raw)
In-Reply-To: <8d91c3a0-3db4-0a7a-ae13-299adb444bd6@linux.intel.com>


Avoid counting of struct pollfd *entries objects with
fdarray_flag__nonfilterable flag by fdarray__filter().
Nonfilterable objects are still processed if requested
revents have been signaled for them.
