Subject: [PATCH 2/4] io_uring: add REQ_F_APOLL_MULTISHOT for requests
Date: Sat, 7 May 2022 22:06:18 +0800 [thread overview]
Message-ID: <[email protected]> (raw)
In-Reply-To: <[email protected]>
From: Hao Xu <[email protected]>
Add a flag to indicate multishot mode for fast poll. currently only
accept use it, but there may be more operations leveraging it in the
future. Also add a mask IO_APOLL_MULTI_POLLED which stands for
REQ_F_APOLL_MULTI | REQ_F_POLLED, to make the code short and cleaner.
