[PATCH openEuler-1.0-LTS] notifiers: Add oops check in blocking_notifier_call_chain()
by Yi Yang 28 Oct '25

28 Oct '25

hulk inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/ID3W9Y ------------------ In hrtimer_interrupt(), interrupts are disabled when acquiring a spinlock, which subsequently triggers an oops. During the oops call chain, blocking_notifier_call_chain() invokes _cond_resched, ultimately leading to a hard lockup.
