Subject: [PATCH] iommu/amd: Remove create_workqueue
Date: Sat, 18 Jun 2016 13:58:30 +0530 [thread overview]
Message-ID: <20160618082830.GA6631@Karyakshetra> (raw)
alloc_workqueue replaces deprecated create_workqueue().
A dedicated workqueue has been used since the workitem (viz
&fault->work), is involved in IO page-fault handling.
WQ_MEM_RECLAIM has been set to guarantee forward progress under memory
pressure, which is a requirement here.
Since there are only a fixed number of work items, explicit concurrency
limit is unnecessary.
