Subject: [PATCH v10 03/15] tools/libperf: avoid counting of nonfilterable fdarray fds
Date: Wed, 8 Jul 2020 10:47:02 +0300 [thread overview]
Message-ID: <f7eedac1-fb94-c203-e1a8-fd399451b534@linux.intel.com> (raw)
In-Reply-To: <4af50c95-36f6-7a61-5a22-2949970fe7a5@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
events have been signaled for them.
