From 81baf90af2dcc8259e99e2f236024524b55313fc Mon Sep 17 00:00:00 2001 From: Bhaktipriya Shridhar Date: Wed, 8 Jun 2016 01:57:19 +0530 Subject: [PATCH] bcache: Remove deprecated create_workqueue alloc_workqueue replaces deprecated create_workqueue(). Dedicated workqueues have been used since bcache_wq and moving_gc_wq are workqueues for writes and are being used on a memory reclaim path. WQ_MEM_RECLAIM has been set to ensure forward progress under memory pressure. Since there are only a fixed number of work items, explicit concurrency limit is unnecessary here.
