Subject: [PATCH v4 23/26] io_uring: don't quiesce intial files register
Date: Thu,  1 Apr 2021 15:44:02 +0100	[thread overview]
Message-ID: <563bb8060bb2d3efbc32fce6101678281c574d2a.1617287883.git.asml.silence@gmail.com> (raw)
In-Reply-To: <[email protected]>

There is no reason why we would want to fully quiesce ring on
IORING_REGISTER_FILES, if it's already registered we fail.
