[PATCH 0/2] fix task_work interation with freezing

[Pavel Begunkov <asml.silence@gmail.com>]

It's reported [1] that a task_work queued at a wrong time can prevent
freezing and make the tasks to spin in get_signal() taking 100%
of CPU. Patch 1 is a preparation. Patch 2 addresses the issue.

Pavel Begunkov (2):
  io_uring/io-wq: limit retrying worker initialisation
  signal: rerun task_work while freezing
