Subject: [PATCH v2 2/3] io_uring/cmd: inline io_uring_cmd_do_in_task_lazy
Date: Fri, 1 Dec 2023 00:57:36 +0000 [thread overview]
Message-ID: <2ec9fb31dd192d1c5cf26d0a2dec5657d88a8e48.1701391955.git.asml.silence@gmail.com> (raw)
In-Reply-To: <[email protected]>
Now as we can easily include io_uring_types.h, move IOU_F_TWQ_LAZY_WAKE
and inline io_uring_cmd_do_in_task_lazy().
