Merge tag 'probes-fixes-v7.3-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-traceHEADmaster
Pull probes fixes from Masami Hiramatsu:
- fprobe: Use guard(rcu_sched_notrace) and check rcu_is_watching()
Exit handlers early if !rcu_is_watching() to prevent potential
use-after-free during unregistration in idle/quiescent states. Switch
to guard(rcu_sched_notrace) to avoid fast-path lockdep overhead and
recursion while ensuring safe grace period synchronization.
- kprobes: Skip disarmed probes when checking optkprobe overlap
Continue past disarmed or unprepared probes in get_optimized_kprobe()
to find active optimized probes. This avoids overwriting active jump
displacements which can lead to panic.
