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

net: ipa: Remove redundant pm_runtime_mark_last_busy() calls

2025-10-30T01:55:56+00:00

pm_runtime_put_autosuspend(), pm_runtime_put_sync_autosuspend(), pm_runtime_autosuspend() and pm_request_autosuspend() now include a call to pm_runtime_mark_last_busy(). Remove the now-reduntant explicit call to pm_runtime_mark_last_busy().

Pull power management updates from Rafael Wysocki: "From the functional perspective, the most significant change here is the addition of support for Energy Models that can be updated dynamically at run time. There is also the addition of LZ4 compression support for hibernation, the new preferred core support in amd-pstate, new platforms support in the Intel RAPL driver, new model-specific EPP handling in intel_pstate and more. Apart from that, the cpufreq default transition delay is reduced from 10 ms to 2 ms (along with some related adjustments), the system suspend statistics code undergoes a significant rework and there is a usual bunch of fixes and code cleanups all over. Specifics: - Allow the Energy Model to be updated dynamically (Lukasz Luba) - Add support for LZ4 compression algorithm to the hibernation image creation and loading code (Nikhil V) - Fix and clean up system suspend statistics collection (Rafael Wysocki) - Simplify device suspend and resume handling in the power management core code (Rafael Wysocki) - Fix PCI hibernation support description (Yiwei Lin) - Make hibernation take set_memory_ro() return values into account as appropriate (Christophe Leroy) - Set mem_sleep_current during kernel command line setup to avoid an ordering issue with handling it (Maulik Shah) - Fix wake IRQs handling when pm_runtime_force_suspend() is used as a driver's system suspend callback (Qingliang Li) - Simplify pm_runtime_get_if_active() usage and add a replacement for pm_runtime_put_autosuspend() (Sakari Ailus) - Add a tracepoint for runtime_status changes tracking (Vilas Bhat) - Fix section title markdown in the runtime PM documentation (Yiwei Lin) - Enable preferred core support in the amd-pstate cpufreq driver (Meng Li) - Fix min_perf assignment in amd_pstate_adjust_perf() and make the min/max limit perf values in amd-pstate always stay within the (highest perf, lowest perf) range (Tor Vic, Meng Li) - Allow intel_pstate to assign model-specific values to strings used in the EPP sysfs interface and make it do so on Meteor Lake (Srinivas Pandruvada) - Drop long-unused cpudata::prev_cummulative_iowait from the intel_pstate cpufreq driver (Jiri Slaby) - Prevent scaling_cur_freq from exceeding scaling_max_freq when the latter is an inefficient frequency (Shivnandan Kumar) - Change default transition delay in cpufreq to 2ms (Qais Yousef) - Remove references to 10ms minimum sampling rate from comments in the cpufreq code (Pierre Gondois) - Honour transition_latency over transition_delay_us in cpufreq (Qais Yousef) - Stop unregistering cpufreq cooling on CPU hot-remove (Viresh Kumar) - General enhancements / cleanups to ARM cpufreq drivers (tianyu2, Nícolas F.

PM: runtime: Simplify pm_runtime_get_if_active() usage

2024-02-12T15:57:47+00:00

There are two ways to opportunistically increment a device's runtime PM usage count, calling either pm_runtime_get_if_active() or pm_runtime_get_if_in_use(). The former has an argument to tell whether to ignore the usage count or not, and the latter simply calls the former with ign_usage_count set to false. The other users that want to ignore the usage_count will have to explicitly set that argument to true which is a bit cumbersome. To make this function more practical to use, remove the ign_usage_count argument from the function. The main implementation is in a static function called pm_runtime_get_conditional() and implementations of pm_runtime_get_if_active() and pm_runtime_get_if_in_use() are moved to runtime.c.
