Subject: [PATCH 3/4] scsi: ufs: use WQ_HIGHPRI for gating work
Date: Mon, 5 Oct 2020 15:36:34 -0700 [thread overview]
Message-ID: <20201005223635.2922805-3-jaegeuk@kernel.org> (raw)
In-Reply-To: <20201005223635.2922805-1-jaegeuk@kernel.org>
From: Jaegeuk Kim <jaegeuk@google.com>
Must have WQ_MEM_RECLAIM
``WQ_MEM_RECLAIM``
All wq which might be used in the memory reclaim paths **MUST**
have this flag set. The wq is guaranteed to have at least one
execution context regardless of memory pressure.
