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) Signed-off-by: Bart Van Assche <bvanassche@acm.org> --- drivers/scsi/bfa/bfad_im.c | 3 ++- drivers/scsi/bnx2fc/bnx2fc_fcoe.c | 4 ++-- drivers/scsi/device_handler/scsi_dh_rdac.c | 3 ++- drivers/scsi/elx/efct/efct_lio.c | 3 ++- drivers/scsi/esas2r/esas2r_init.c | 3 ++- drivers/scsi/fcoe/fcoe_sysfs.c | 8 ++++---- drivers/scsi/fnic/fnic_main.c | 6 ++++-- drivers/scsi/hisi_sas/hisi_sas_main.c | 3 ++- drivers/scsi/ibmvscsi_tgt/ibmvscsi_tgt.c | 2 +- drivers/scsi/libfc/fc_exch.c | 3 ++- drivers/scsi/libfc/fc_rport.c | 3 ++- drivers/scsi/libsas/sas_init.c | 4 ++-- drivers/scsi/megaraid/megaraid_sas_fusion.c | 4 ++-- drivers/scsi/mpi3mr/mpi3mr_fw.c | 4 ++-- drivers/scsi/mpt3sas/mpt3sas_base.c | 4 ++-- drivers/scsi/myrb.c | 3 ++- drivers/scsi/myrs.c | 3 ++- drivers/scsi/qedf/qedf_main.c | 13 +++++++------ drivers/scsi/qedi/qedi_main.c | 6 ++++-- drivers/scsi/qla2xxx/qla_os.c | 6 ++++-- drivers/scsi/qla4xxx/ql4_os.c | 2 +- drivers/scsi/snic/snic_main.c | 6 ++++-- drivers/scsi/stex.c | 3 ++- drivers/scsi/vmw_pvscsi.c | 3 ++- drivers/ufs/core/ufshcd.c | 5 +++-- 25 files changed, 64 insertions(+), 43 deletions(-)
