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

Convert 'alloc_obj' family to use the new default GFP_KERNEL argument

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

usbip: Reduce CONNRESET message noise in dmesg from stub

stub_complete() prints informational messages for each urb unlink filling dmesg. Change the message to dev_dbg() similar to vhci reports the CONNRESET condition.

usbip: Use min to simplify stub_send_ret_submit

2025-10-22T08:58:31+00:00

Use min() to improve stub_send_ret_submit(). Change the local variable 'size' from 'int' to 'unsigned int' to prevent a signedness error and to match the resulting type.

usb: vhci-hcd: Replace pr_() with dev_() logging

2025-10-13T07:35:16+00:00

Where possible, use driver model logging helpers dev_*() instead of pr_*() to ensure the messages are always associated with the corresponding device/driver. While at it, join the split strings to make checkpatch happy and regain ability to grep for those log messages in the source code: WARNING: quoted string split across lines Acked-by: Shuah Khan Signed-off-by: Cristian Ciocaltea Link: https://lore.kernel.org/r/20251008-vhci-hcd-cleanup-v2-2-b6acc4dd6e44@collabora.com Signed-off-by: Greg Kroah-Hartman

usbip: Fix locking bug in RT-enabled kernels

2025-10-13T07:11:49+00:00

Interrupts are disabled before entering usb_hcd_giveback_urb(). A spinlock_t becomes a sleeping lock on PREEMPT_RT, so it cannot be acquired with disabled interrupts.

usb: vhci-hcd: Prevent suspending virtually attached devices

2025-09-25T16:52:32+00:00

The VHCI platform driver aims to forbid entering system suspend when at least one of the virtual USB ports are bound to an active USB/IP connection. However, in some cases, the detection logic doesn't work reliably, i.e. when all devices attached to the virtual root hub have been already suspended, leading to a broken suspend state, with unrecoverable resume. Ensure the virtually attached devices do not enter suspend by setting the syscore PM flag. Note this is currently limited to the client side only, since the server side doesn't implement system suspend prevention.
