Subject: [PATCH 2/6] fs: add kiocb alloc cache flag
Date: Wed, 11 Aug 2021 13:35:29 -0600 [thread overview]
Message-ID: <20210811193533.766613-3-axboe@kernel.dk> (raw)
In-Reply-To: <20210811193533.766613-1-axboe@kernel.dk>
If this kiocb can safely use the polled bio allocation cache, then this
flag must be set.
