Message-ID: <20230124023834.106339-9-ericvh@kernel.org> (raw)
In-Reply-To: <20230124023834.106339-1-ericvh@kernel.org>
Add some additional mount modes for cache management including
specifying directio as a mount option and an option for ignore
qid.version for determining whether or not a file is cacheable.
