From ab4c1f9f686836e7a772af0c6dd71fe9efa2609c Mon Sep 17 00:00:00 2001 From: Alexey Budankov Date: Fri, 17 Jul 2020 09:59:45 +0300 Subject: libperf: Add flags to fdarray fds objects Store flags per struct pollfd *entries object in a bitmap of int size. Implement fdarray_flag__nonfilterable flag to skip object from counting by fdarray__filter(). Fixed fdarray test issue reported by kernel test robot.
