11 daysConvert 'alloc_obj' family to use the new default GFP_KERNEL argumentLinus Torvalds-40/+40
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. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
12 daystreewide: Replace kmalloc with kmalloc_obj for non-scalar typesKees Cook-41/+41
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 <kees@kernel.org>

2026-01-24Input: i8042 - add quirk for ASUS Zenbook UX425QA_UM425QAfeng-0/+11
The ASUS Zenbook UX425QA_UM425QA fails to initialize the keyboard after a cold boot. A quirk already exists for "ZenBook UX425", but some Zenbooks report "Zenbook" with a lowercase 'b'. Since DMI matching is case-sensitive, the existing quirk is not applied to these "extra special" Zenbooks. Testing confirms that this model needs the same quirks as the ZenBook UX425 variants.

2025-10-01Drivers: hv: Add CONFIG_HYPERV_VMBUS optionMukesh Rathor-2/+2
At present VMBus driver is hinged off of CONFIG_HYPERV which entails lot of builtin code and encompasses too much. It's not always clear what depends on builtin hv code and what depends on VMBus. Setting CONFIG_HYPERV as a module and fudging the Makefile to switch to builtin adds even more confusion. VMBus is an independent module and should have its own config option. Also, there are scenarios like baremetal dom0/root where support is built in with CONFIG_HYPERV but without VMBus. Lastly, there are more features coming down that use CONFIG_HYPERV and add more dependencies on it. So, create a fine grained HYPERV_VMBUS option and update Kconfigs for dependency on VMBus.

2025-01-15Input: i8042 - Add support for platform filter contextsArmin Wolf-7/+10
Currently the platform filter cannot access any driver-specific state which forces drivers installing a i8042 filter to have at least some kind of global pointer for their filter. Allow callers of i8042_install_filter() to submit a context pointer which is then passed to the i8042 filter. This frees drivers from the responsibility of having to manage this global pointer themself. Also introduce a separate type for the i8042 filter (i8042_filter_t) so that the function definitions can stay compact. Tested on a Dell Inspiron 3505.

After commit 0edb555a65d1 ("platform: Make platform_driver::remove() return void") .remove() is (again) the right callback to implement for platform drivers. Convert all platform drivers below drivers/input/ to use .remove(), with the eventual goal to drop struct platform_driver::remove_new(). As .remove() and .remove_new() have the same prototypes, conversion is done by just changing the structure member name in the driver initializer. While touching these files, make indention of the struct initializer consistent in a few drivers.

2024-09-27[tree-wide] finally take no_llseek outAl Viro-1/+0
no_llseek had been defined to NULL two years ago, in commit 868941b14441 ("fs: remove no_llseek") To quote that commit, At -rc1 we'll need do a mechanical removal of no_llseek - git grep -l -w no_llseek | grep -v porting.rst | while read i; do sed -i '/\<no_llseek\>/d' $i done would do it. Unfortunately, that hadn't been done. Linus, could you do that now, so that we could finally put that thing to rest? All instances are of the form .llseek = no_llseek, so it's obviously safe.
