Linus Torvalds bf4afc53b7 Convert 'alloc_obj' family to use the new default GFP_KERNEL argument
This was done entirely with mindless brute force, using

    git grep -l '\<k[vmz]*alloc_objs*(.*, GFP_KERNEL)' |
        xargs sed -i 's/\(alloc_objs*(.*\), GFP_KERNEL)/\1)/'

to convert the new alloc_obj() users that had a simple GFP_KERNEL
argument to just drop that argument.

Note that due to the extreme simplicity of the scripting, any slightly
more complex cases spread over multiple lines would not be triggered:
they definitely exist, but this covers the vast bulk of the cases, and
the resulting diff is also then easier to check automatically.

For the same reason the 'flex' versions will be done as a separate
conversion.

Kees Cook 69050f8d6d treewide: Replace kmalloc with kmalloc_obj for non-scalar types
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 *".

Bart Van AsscheandMartin K. Petersen 0db3f51839 scsi: Change the return type of the .queuecommand() callback
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.

Bart Van AsscheandMartin K. Petersen 0ea163a18b scsi: usb: Rename the RESERVE and RELEASE constants
The names RESERVE and RELEASE are not only used in <scsi/scsi_proto.h> but
also elsewhere in the kernel:

$ git grep -nHE 'define[[:blank:]]*(RESERVE|RELEASE)[[:blank:]]'
drivers/input/joystick/walkera0701.c:13:#define RESERVE 20000
drivers/s390/char/tape_std.h:56:#define RELEASE			0xD4	/* 3420 NOP, 3480 REJECT */
drivers/s390/char/tape_std.h:58:#define RESERVE			0xF4	/* 3420 NOP, 3480 REJECT */

Additionally, while the names of the symbolic constants RESERVE_10 and
RELEASE_10 include the command length, the command length is not included
in the RESERVE and RELEASE names. Address both issues by renaming the
RESERVE and RELEASE constants into RESERVE_6 and RELEASE_6 respectively.
