Subject: [PATCHSET 0/2] tw/wakeup tweaks
Date: Sat, 17 Dec 2022 13:48:38 -0700 [thread overview]
Message-ID: <20221217204840.45213-1-axboe@kernel.dk> (raw)
Hi,
One patch tweaks when we think we have task_work pending to be more
inclusive rather than gate on TIF_NOTIFY_SIGNAL, patch two ensures we
don't do extra loops io_cqring_wait() - and just as importantly, that
the expected run path for task_work will not have the task itself
adding to the ctx->cq_wait waitqueue.
