scsi: fnic: Make fnic_queuecommand() easier to analyze

2026-02-28T22:17:39+00:00

Move a spin_unlock_irqrestore() call such that the io_lock_acquired variable can be eliminated. This patch prepares for enabling the Clang thread-safety analyzer.

scsi: fnic: Refactor in_remove flag and call to fnic_fcpio_reset()

2026-02-24T19:09:24+00:00

Modify logic to remove unnecessary acquire/release of spinlock to set in_remove flag. There's also no need to check for init status to call fnic_fcpio_reset.

scsi: fnic: Do not use GFP_ZERO for mempools

2026-02-24T19:09:24+00:00

One cannot use the GFP_ZERO flag for mempool allocation, so use memset() instead.

scsi: fnic: Use mempool for receive frames

2026-02-24T19:09:23+00:00

The receive frames are constantly replenished so we should rather use a mempool here. fip_frame_queue is an rxq. Deallocate it in fnic_free_rxq().

treewide: Replace kmalloc with kmalloc_obj for non-scalar types

2026-02-21T09:02:28+00:00

This is the result of running the Coccinelle script from scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to avoid scalar types (which need careful case-by-case checking), and instead replace kmalloc-family calls that allocate struct or union object instances: Single allocations: kmalloc(sizeof(TYPE), ...) are replaced with: kmalloc_obj(TYPE, ...) Array allocations: kmalloc_array(COUNT, sizeof(TYPE), ...) are replaced with: kmalloc_objs(TYPE, COUNT, ...) Flex array allocations: kmalloc(struct_size(PTR, FAM, COUNT), ...) are replaced with: kmalloc_flex(*PTR, FAM, COUNT, ...) (where TYPE may also be *VAR) The resulting allocations no longer return "void *", instead returning "TYPE *". Signed-off-by: Kees Cook

scsi: Change the return type of the .queuecommand() callback

2026-01-24T02:32:34+00:00

In clang version 21.1 and later the -Wimplicit-enum-enum-cast warning option has been introduced. This warning is enabled by default and can be used to catch .queuecommand() implementations that return another value than 0 or one of the SCSI_MLQUEUE_* constants. Hence this patch that changes the return type of the .queuecommand() implementations from 'int' into 'enum scsi_qc_status'. No functionality has been changed.
