2025-06-24rust: sync: Mark CondVar::notify_*() inlineKunwu Chan
When build the kernel using the llvm-18.1.3-rust-1.85.0-x86_64 with ARCH=arm64, the following symbols are generated: $nm vmlinux | grep ' _R'.*CondVar | rustfilt ... T <kernel::sync::condvar::CondVar>::notify_all ... T <kernel::sync::condvar::CondVar>::notify_one ... T <kernel::sync::condvar::CondVar>::notify_sync ... These notify_*() symbols are trivial wrappers around the C functions __wake_up() and __wake_up_sync(). It doesn't make sense to go through a trivial wrapper for these functions, so mark them inline.

2025-06-18sched/core: Reorganize cgroup bandwidth control interface file writesTejun Heo
- Move input parameter validation from tg_set_cfs_bandwidth() to the new outer function tg_set_bandwidth(). The outer function handles parameters in usecs, validates them and calls tg_set_cfs_bandwidth() which converts them into nsecs. This matches tg_bandwidth() on the read side. - max/min_cfs_* consts are now used by tg_set_bandwidth(). Relocate, convert into usecs and drop "cfs" from the names. - Reimplement cpu_cfs_{period|quote|burst}_write_*() using tg_bandwidth() and tg_set_bandwidth() and replace "cfs" in the names with "bw". - Update cpu_max_write() to use tg_set_bandiwdth(). cpu_period_quota_parse() is updated to drop nsec conversion accordingly. This aligns the behavior with cfs_period_quota_print(). - Drop now unused tg_set_cfs_{period|quota|burst}(). - While at it, for consistency, rename default_cfs_period() to default_bw_period_us() and make it return usecs. This is to prepare for adding bandwidth control support to sched_ext. tg_set_bandwidth() will be used as the muxing point. No functional changes intended.

2025-06-18sched/core: Reorganize cgroup bandwidth control interface file readsTejun Heo
- Update tg_get_cfs_*() to return u64 values. These are now used as the low level accessors to the fair's bandwidth configuration parameters. Translation to usecs takes place in these functions. - Add tg_bandwidth() which reads all three bandwidth parameters using tg_get_cfs_*(). - Reimplement cgroup interface read functions using tg_bandwidth(). Drop cfs from the function names. This is to prepare for adding bandwidth control support to sched_ext. tg_bandwidth() will be used as the muxing point similar to tg_weight(). No functional changes.

2025-06-13sched/smp: Make SMP unconditionalIngo Molnar
Simplify the scheduler by making CONFIG_SMP=y primitives and data structures unconditional. Introduce transitory wrappers for functionality not yet converted to SMP. Note that this patch is pretty large, because there's no clear separation between various aspects of the SMP scheduler, it's basically a huge block of #ifdef CONFIG_SMP. A fair amount of it has to be switched on for it to boot and work on UP systems.

2025-06-11sched: Make clangd usablePeter Zijlstra
Due to the weird Makefile setup of sched the various files do not compile as stand alone units. The new generation of editors are trying to do just this -- mostly to offer fancy things like completions but also better syntax highlighting and code navigation. Specifically, I've been playing around with neovim and clangd. Setting up clangd on the kernel source is a giant pain in the arse (this really should be improved), but once you do manage, you run into dumb stuff like the above. Fix up the scheduler files to at least pretend to work.
