scsi: ses: Handle positive SCSI error from ses_recv_diag()

2026-03-20T01:33:28+00:00

ses_recv_diag() can return a positive value, which also means that an error happened, so do not only test for negative values. Cc: James E.J. Bottomley Cc: Martin K.

Convert more 'alloc_obj' cases to default GFP_KERNEL arguments

2026-02-22T04:03:00+00:00

This converts some of the visually simpler cases that have been split over multiple lines. I only did the ones that are easy to verify the resulting diff by having just that final GFP_KERNEL argument on the next line. Somebody should probably do a proper coccinelle script for this, but for me the trivial script actually resulted in an assertion failure in the middle of the script. I probably had made it a bit _too_ trivial. So after fighting that far a while I decided to just do some of the syntactically simpler cases with variations of the previous 'sed' scripts. The more syntactically complex multi-line cases would mostly really want whitespace cleanup anyway. Signed-off-by: Linus Torvalds

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: ses: Fix devices attaching to different hosts

2026-02-18T02:26:46+00:00

On a multipath SAS system some devices don't end up with correct symlinks from the SCSI device to its enclosure. Some devices even have enclosure links pointing to enclosures attached to different SCSI hosts. ses_match_to_enclosure() calls enclosure_for_each_device() which iterates over all enclosures on the system, not just enclosures attached to the current SCSI host. Replace the iteration with a direct call to ses_enclosure_find_by_addr().

scsi: ses: Convert to SCSI bus methods

2026-01-12T02:31:58+00:00

The SCSI subsystem has implemented dedicated callbacks for probe, remove and shutdown. Make use of them. This fixes a runtime warning about the driver needing to be converted to the bus probe method. There is no need for an empty remove callback, no remove callback has the same semantics. So instead of converting the remove callback, drop it.

scsi: core: Pass a struct scsi_driver to scsi_{,un}register_driver()

This aligns with what other subsystems do, reduces boilerplate a bit for device drivers and is less error prone.

move asm/unaligned.h to linux/unaligned.h

asm/unaligned.h is always an include of asm-generic/unaligned.h; might as well move that thing to linux/unaligned.h and include that - there's nothing arch-specific in that header. auto-generated by the following: for i in `git grep -l -w asm/unaligned.h`; do sed -i -e "s/asm\/unaligned.h/linux\/unaligned.h/" $i done for i in `git grep -l -w asm-generic/unaligned.h`; do sed -i -e "s/asm-generic\/unaligned.h/linux\/unaligned.h/" $i done git mv include/asm-generic/unaligned.h include/linux/unaligned.h git mv tools/include/asm-generic/unaligned.h tools/include/linux/unaligned.h sed -i -e "/unaligned.h/d" include/asm-generic/Kbuild sed -i -e "s/__ASM_GENERIC/__LINUX/" include/linux/unaligned.h tools/include/linux/unaligned.h
