Subject: [PATCH for-next v3 3/3] io_uring/rw: enable bio caches for IRQ rw
Date: Fri, 21 Oct 2022 11:34:07 +0100 [thread overview]
Message-ID: <aab3521d49fd6c1ff6ea194c9e63d05565efc103.1666347703.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.
