Subject: [PATCH v4 01/34] mm: Add PAGE_TYPE_OP folio functions
Date: Mon, 12 Jun 2023 14:03:50 -0700 [thread overview]
Message-ID: <20230612210423.18611-2-vishal.moola@gmail.com> (raw)
In-Reply-To: <20230612210423.18611-1-vishal.moola@gmail.com>
No folio equivalents for page type operations have been defined, so
define them for later folio conversions.
Also changes the Page##uname macros to take in const struct page* since
we only read the memory here.
