Subject: Re: [PATCH 0/4] add struct page and Direct I/O support to reserved memory
Date: Mon, 11 Jul 2022 08:01:32 -0700	[thread overview]
Message-ID: <Ysw7TMFO8Mw0nq8x@infradead.org> (raw)
In-Reply-To: <20220711122459.13773-1-me@linux.beauty>

Who is going to use it and how?  Because normally the reserved memory
is used through the DMA allocator, and you can't just do direct I/O
to that.
