5.4-stable included a backport of: Author: Eric W. Biederman <ebiederm@xmission.com> Date: Thu Dec 3 14:11:13 2020 -0600 rwsem: Implement down_read_interruptible [ Upstream commit 31784cff7ee073b34d6eddabb95e3be2880a425c ] In preparation for converting exec_update_mutex to a rwsem so that multiple readers can execute in parallel and not deadlock, add down_read_interruptible. This is needed for perf_event_open to be converted (with no semantic changes) from working on a mutex to wroking on a rwsem. Signed-off-by: Eric W. Biederman <ebiederm@xmission.com> Signed-off-by: Peter Zijlstra (Intel) <peterz@infradead.org> Link: https://lkml.kernel.org/r/87k0tybqfy.fsf@x220.int.ebiederm.org Signed-off-by: Sasha Levin <sashal@kernel.org> We implement a -rt variant to fix the build issues.
