Type Alias KernelRawMutex 

pub type KernelRawMutex = RawSpinNoIrq;

Raw mutex used as the L type parameter for the kprobe crate’s ProbeManager / Kprobe / Kretprobe (the perf subsystem refers to the concrete probe types parameterized on it — see KernelKprobe / KernelKretprobe).

Backed by ax_kspin::RawSpinNoIrq, which disables kernel preemption and local IRQs across the critical section (NoPreemptIrqSave semantics, the same as the rest of the kernel’s spin locks). This matters because the lock is taken on trap / kprobe-callback paths: a plain atomic spin lock that left preemption and IRQs enabled could be re-entered on the same CPU and would then deadlock spinning on a lock it already holds.
