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

This was done entirely with mindless brute force, using git grep -l '\

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

treewide, timers: Rename from_timer() to timer_container_of()

Move this API to the canonical timer_*() namespace. [ tglx: Redone against pre rc1 ] Signed-off-by: Ingo Molnar Signed-off-by: Thomas Gleixner Link: https://lore.kernel.org/all/aB2X0jCKQO56WdMt@gmail.com

treewide: Switch/rename to timer_delete[_sync]()

2025-04-05T08:30:12+00:00

timer_delete[_sync]() replaces del_timer[_sync](). Convert the whole tree over and remove the historical wrapper inlines. Conversion was done with coccinelle plus manual fixups where necessary. Signed-off-by: Thomas Gleixner Signed-off-by: Ingo Molnar

leds: Change led_trigger_blink[_oneshot]() delay parameters to pass-by-value

2023-05-25T11:16:27+00:00

led_blink_set[_oneshot]()'s delay_on and delay_off function parameters are pass by reference, so that hw-blink implementations can report back the actual achieved delays when the values have been rounded to something the hw supports. This is really only interesting for the sysfs API / the timer trigger. Other triggers don't really care about this and none of the callers of led_trigger_blink[_oneshot]() do anything with the returned delay values. Change the led_trigger_blink[_oneshot]() delay parameters to pass-by-value, there are 2 reasons for this: 1. led_cdev->blink_set() may sleep, while led_trigger_blink() may not. So on hw where led_cdev->blink_set() sleeps the call needs to be deferred to a workqueue, in which case the actual achieved delays are unknown (this is a preparation patch for the deferring). 2. Since the callers don't care about the actual achieved delays, allowing callers to directly pass a value leads to simpler code for most callers.

mac80211: don't open-code LED manipulations

2021-06-23T09:29:12+00:00

We shouldn't open-code led_trigger_blink() or led_trigger_event(), use them instead of badly open-coding them. This also fixes the locking, led_trigger_blink() and led_trigger_event() now use read_lock_irqsave().

leds: triggers: let struct led_trigger::activate() return an error code

2018-07-05T21:21:10+00:00

Given that activating a trigger can fail, let the callback return an indication. This prevents to have a trigger active according to the "trigger" sysfs attribute but not functional. All users are changed accordingly to return 0 for now. There is no intended change in behaviour. Signed-off-by: Uwe Kleine-König Acked-by: Pavel Machek Signed-off-by: Jacek Anaszewski

In preparation for unconditionally passing the struct timer_list pointer to all timer callbacks, switch to using the new timer_setup() and from_timer() to pass the timer pointer explicitly.

mac80211: fix throughput LED trigger

2015-05-11T17:16:04+00:00

As I was testing with hwsim, I missed that my previous commit to make LED work depend on activation broke the code because I missed removing the old trigger struct and some code was still using it, now erroneously, causing crashes. Fix this by always using the correct struct. Reported-by: Felix Fietkau Tested-by: Felix Fietkau Signed-off-by: Johannes Berg
