kernel: stop masking signals in create_io_thread()
[ Upstream commit b16b3855 ] This is racy - move the blocking into when the task is created and we're marking it as PF_IO_WORKER anyway. The IO threads are now prepared to handle signals like SIGSTOP as well, so clear that from the mask to allow proper stopping of IO threads. Acked-by:"Eric W.
