Subject: [PATCH 4/4] Allow MEMCG on PREEMPT_RT
Date: Tue, 12 Jul 2022 13:22:38 +0200	[thread overview]
Message-ID: <20220712112238.18824-5-goliath@infraroot.at> (raw)
In-Reply-To: <20220712112238.18824-1-goliath@infraroot.at>

With these backported, it is safe to use MEMCG again:
mm/memcg: Add a local_lock_t for IRQ and TASK object.
mm/memcg: Protect per-CPU counter by disabling preemption on PREEMPT_RT where needed.
mm/memcg: Disable threshold event handlers on PREEMPT_RT
