Eric Dumazet 3c9c708c9f block: avoid infinite loop in get_task_io_context() ... Calling get_task_io_context() on a exiting task which isn't %current can loop forever. This triggers at boot time on my dev machine. BUG: soft lockup - CPU#3 stuck for 22s ! [mountall.1603] Fix this by making create_task_io_context() returns -EBUSY in this case to break the loop.
