Subject: [RFC for-next 4/4] io_uring/rw: enable bio caches for IRQ rw
Date: Tue, 18 Oct 2022 19:47:16 +0100	[thread overview]
Message-ID: <11cf38513c45083955d4ee2cedbb46df0a9f6081.1666114003.git.asml.silence@gmail.com> (raw)
In-Reply-To: <[email protected]>

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