2025-06-24rust: task: Add Rust version of might_sleep()FUJITA Tomonori
Add a helper function equivalent to the C's might_sleep(), which serves as a debugging aid and a potential scheduling point. Note that this function can only be used in a nonatomic context. This will be used by Rust version of read_poll_timeout().

2025-06-24rust: Introduce file_from_location()Boqun Feng
Most of kernel debugging facilities take a nul-terminated string for file names for a callsite (generated from __FILE__), however the Rust courterpart, Location, would return a Rust string (not nul-terminated) from method .file(). And such a string cannot be passed to C debugging function directly. There is ongoing work to support a Location::file_with_nul() [1], which returns a nul-terminated string from a Location. Since it's still working in progress, and it will take some time before the feature finally gets stabilized and the kernel's minimal rustc version might also take a while to bump to a version that at least has that feature, introduce a file_from_location() function, which returns a warning string if Location::file_with_nul() is not available. This should work in most cases because as for now the known usage of Location::file_with_nul() is only in debugging code (e.g. might_sleep()) and there might be other information reported by the debugging code that could help locate the problematic function, so missing the file name is fine at the moment.

When building the kernel using the llvm-18.1.3-rust-1.85.0-x86_64 toolchain provided by kernel.org, the following symbols are generated: $ nm vmlinux | grep ' _R'.*Task | rustfilt ...

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.

- 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.

Simplify the scheduler by making the CONFIG_SMP=y version of idle_thread_set_boot_cpu() unconditional. Note that idle_thread_set_boot_cpu() is already conditional on CONFIG_GENERIC_SMP_IDLE_THREAD, which most architectures select unconditionally on both UP and SMP kernels.

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.
