Subject: [RFC for-next v2 4/4] io_uring/rw: enable bio caches for IRQ rw
Date: Tue, 18 Oct 2022 20:50:58 +0100	[thread overview]
Message-ID: <f43faaa420b95066bdc7679aee411cb4edd160d4.1666122465.git.asml.silence@gmail.com> (raw)
In-Reply-To: <cover.1666122465.git.asml.silence@gmail.com>

Now we can use IOCB_ALLOC_CACHE not only for iopoll'ed reads/write but
also for normal IRQ driven I/O.
