Subject: [PATCH AUTOSEL 5.15 24/25] dm cache: add cond_resched() to various workqueue loops
Date: Sun, 26 Feb 2023 21:08:47 -0500 [thread overview]
Message-ID: <20230227020855.1051605-24-sashal@kernel.org> (raw)
In-Reply-To: <20230227020855.1051605-1-sashal@kernel.org>
From: Mike Snitzer <snitzer@kernel.org>
[ Upstream commit 76227f6dc805e9e960128bcc6276647361e0827c ]
Otherwise on resource constrained systems these workqueues may be too
greedy.
