linux.git/rust/helpers/cpu.c, branch v6.18.21 Clone of https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git rust: cpu: Add CpuId::current() to retrieve current CPU ID 2025-06-12T05:01:28+00:00 Viresh Kumar viresh.kumar@linaro.org 2025-06-09T11:14:16+00:00 c7f005f70d22cd5613cac30bf6d34867189e36a9 Introduce `CpuId::current()`, a constructor that wraps the C function `raw_smp_processor_id()` to retrieve the current CPU identifier without guaranteeing stability. This function should be used only when the caller can ensure that the CPU ID won't change unexpectedly due to preemption or migration.

Introduce `CpuId::current()`, a constructor that wraps the C function
`raw_smp_processor_id()` to retrieve the current CPU identifier without
guaranteeing stability.

This function should be used only when the caller can ensure that
the CPU ID won't change unexpectedly due to preemption or migration.
