#     Merge tag 'task_work-2021-01-19' of git://git.kernel.dk/linux-block
#     
#     Pull task_work fix from Jens Axboe:
#      "The TIF_NOTIFY_SIGNAL change inadvertently removed the unconditional
#       task_work run we had in get_signal().
#     
#       This caused a regression for some setups, since we're relying on eg
#       ____fput() being run to close and release, for example, a pipe and
#       wake the other end.
#     
#       For 5.11, I prefer the simple solution of just reinstating the
#       unconditional run, even if it conceptually doesn't make much sense -
#       if you need that kind of guarantee, you should be using TWA_SIGNAL
#       instead of TWA_NOTIFY. But it's the trivial fix for 5.11, and would
#       ensure that other potential gotchas/assumptions for task_work don't
#       regress for 5.11.
#     
#       We're looking into further simplifying the task_work notifications for
#       5.12 which would resolve that too"
