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: <[email protected]> (raw)
In-Reply-To: <[email protected]>

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.
