Subject: [PATCH 3/6] scsi: ufs: use WQ_HIGHPRI for gating work
Date: Tue, 15 Sep 2020 13:45:29 -0700	[thread overview]
Message-ID: <20200915204532.1672300-3-jaegeuk@kernel.org> (raw)
In-Reply-To: <20200915204532.1672300-1-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.
