Subject: [PATCH 06/13] scripts: get_abi.pl: Ignore fs/cgroup sysfs nodes earlier
Date:   Thu, 23 Sep 2021 15:30:04 +0200
Message-Id: <3e2f5591b350c769cdf1a896c14555f4b7b94e6a.1632402570.git.mchehab+huawei@kernel.org>

MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Sender: Mauro Carvalho Chehab <mchehab@kernel.org>
Precedence: bulk

In order to speedup the parser and store less data, handle
fs/cgroup exceptions a lot earlier.
