The latter then dereferences the freed list head\nafter reacquiring the mutex and can free it a second time.\n\nComplete the list and IDR updates, including freeing an empty list head,\nbefore dropping the mutex. Keep the blocking notifier outside the critical\nsection and retain only the detached request across the callback.",
