scsi: elx: efct: Remove redundant memset() statement

2022-05-20T00:16:26Z

As memset() of bmbx is immediately followed by a memcpy() where bmbx is the destination, the memset() is redundant. Link: https://lore.kernel.org/r/20220505143703.45441-1-harshit.m.mogalapalli@oracle.com Signed-off-by: Harshit Mogalapalli Signed-off-by: Martin K. Petersen

scsi: elx: efct: Remove unnecessary memset() in efct_io()

io->sgl is allocated by kzalloc(). The memory is set to zero. It is unnecessary to call memset again. Link: https://lore.kernel.org/r/20220318145230.1031-1-wanjiabing@vivo.com Signed-off-by: Wan Jiabing Signed-off-by: Martin K. Petersen

Pull SCSI updates from James Bottomley: "This series consists of the usual driver updates (qla2xxx, pm8001, libsas, smartpqi, scsi_debug, lpfc, iscsi, mpi3mr) plus minor updates and bug fixes. The high blast radius core update is the removal of write same, which affects block and several non-SCSI devices.

treewide: Replace zero-length arrays with flexible-array members

2022-02-17T13:00:39Z

There is a regular need in the kernel to provide a way to declare having a dynamically sized set of trailing elements in a structure. Kernel code should always use “flexible array members”[1] for these cases. The older style of one-element or zero-length arrays should no longer be used[2]. This code was transformed with the help of Coccinelle: (next-20220214$ spatch --jobs $(getconf _NPROCESSORS_ONLN) --sp-file script.cocci --include-headers --dir . > output.patch) @@ identifier S, member, array; type T1, T2; @@ struct S { ... T1 member; T2 array[ - 0 ]; }; UAPI and wireless changes were intentionally excluded from this patch and will be sent out separately.

scsi: elx: efct: Don't use GFP_KERNEL under spin lock

2022-01-25T04:30:23Z

GFP_KERNEL/GFP_DMA can't be used under a spin lock. According the comment, els_ios_lock is used to protect els ios list so we can move down the spin lock to avoid using this flag under the lock.

scsi: efct: Remove useless DMA-32 fallback configuration

2022-01-10T15:37:02Z

As stated in [1], dma_set_mask() with a 64-bit mask never fails if dev->dma_mask is non-NULL. So, if it fails, the 32 bits case will also fail for the same reason. Simplify code and remove some dead code accordingly. While at it, return the error code returned by dma_set_mask_and_coherent() instead of -1.

scsi: elx: Use 'bitmap_zalloc()' when applicable

2021-10-27T03:28:33Z

'sli4->ext[i].use_map' is a bitmap. Use 'bitmap_zalloc()' to simplify code, improve the semantic and avoid some open-coded arithmetic in allocator arguments. Also change the corresponding 'kfree()' into 'bitmap_free()' to keep consistency.
