Subject: [PATCH v11 03/15] tools/libperf: avoid counting of nonfilterable fdarray fds
Date: Tue, 14 Jul 2020 12:04:31 +0300	[thread overview]
Message-ID: <7123e415-4b42-1884-18d9-a0e9e150470b@linux.intel.com> (raw)
In-Reply-To: <037d737f-0ada-a9f0-9686-f7521ca6fbc3@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.
