From f5287edae43512faeedc768a1cb2e093c0135ab8 Mon Sep 17 00:00:00 2001 From: Bruce Ashfield Date: Tue, 2 Feb 2021 22:24:02 -0500 Subject: linux-yocto-rt/5.4: fix 5.4-stable caused build breakage 5.4-stable included a backport of: Author: Eric W. Biederman 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.
