Subject: [PATCH 1/1] io_uring: run task_work on io_uring_register()
Date: Sat, 20 Feb 2021 15:17:18 +0000	[thread overview]
Message-ID: <0b6e6404ad89752523d3428669ec089cd540327c.1613834133.git.asml.silence@gmail.com> (raw)
In-Reply-To: <[email protected]>

Do run task_work before io_uring_register(), that might make a first
quiesce round much nicer.
