From b97c0741c7dccedec60524b596c4fa9d6a136523 Mon Sep 17 00:00:00 2001 From: Bart Van Assche Date: Thu, 22 Aug 2024 12:59:05 -0700 Subject: [PATCH 01/18] scsi: Expand all create*_workqueue() invocations The workqueue maintainer wants to remove the create*_workqueue() macros because these macros always set the WQ_MEM_RECLAIM flag and because these only support literal workqueue names. Hence this patch that replaces the create*_workqueue() invocations with the definition of this macro. The WQ_MEM_RECLAIM flag has been retained because I think that flag is necessary for workqueues created by storage drivers. This patch has been generated by running spatch and git clang-format. spatch has been invoked as follows: spatch --in-place --sp-file expand-create-workqueue.spatch $(git grep -lEw 'create_(freezable_|singlethread_|)workqueue' */scsi */ufs) The contents of the expand-create-workqueue.spatch file is as follows: @@ expression name; @@ -create_workqueue(name) +alloc_workqueue("%s", WQ_MEM_RECLAIM, 1, name) @@ expression name; @@ -create_freezable_workqueue(name) +alloc_workqueue("%s", WQ_FREEZABLE | WQ_UNBOUND | WQ_MEM_RECLAIM, 1, name) @@ expression name; @@ -create_singlethread_workqueue(name) +alloc_ordered_workqueue("%s", WQ_MEM_RECLAIM, name) Reviewed-by: Peter Wang Signed-off-by: Bart Van Assche Link: https://lore.kernel.org/r/20240822195944.654691-2-bvanassche@acm.org Signed-off-by: Martin K.
