Subject: [GIT PULL] perf events fix

Linus,

Please pull the latest perf/urgent Git tree from:

   git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git perf-urgent-2024-06-08

   # HEAD: 74751ef5c1912ebd3e65c3b65f45587e05ce5d36 perf/core: Fix missing wakeup when waiting for context reference

Fix race between perf_event_free_task() and perf_event_release_kernel()
that can result in missed wakeups and hung tasks.

 Thanks,

	Ingo
