Subject: [PATCH V3 4/9] io_uring: move marking REQ_F_CQE_SKIP out of io_free_req()
Date: Sat, 11 May 2024 08:12:07 +0800 [thread overview]
Message-ID: <20240511001214.173711-5-ming.lei@redhat.com> (raw)
In-Reply-To: <20240511001214.173711-1-ming.lei@redhat.com>
Prepare for supporting sqe group, which requires to post group leader's
CQE after all members' CQEs are posted. For group leader request, we can't
do that in io_req_complete_post, and REQ_F_CQE_SKIP can't be set in
io_free_req().
So move marking REQ_F_CQE_SKIP out of io_free_req().
No functional change.
