Subject: [PATCH v2 22/24] io_uring: kill off ->inflight_entry field
Date: Fri, 24 Sep 2021 22:00:02 +0100	[thread overview]
Message-ID: <fd8d68087ede26c4e1707ce6b175aa1eb2381f2b.1632516769.git.asml.silence@gmail.com> (raw)
In-Reply-To: <[email protected]>

->inflight_entry is not used anymore after converting everything to
single linked lists, remove it. Also adjust io_kiocb layout, so all hot
bits are in first 3 cachelines.
