Subject: [PATCH v2 2/5] mmzone: Introduce folio_migratetype()
Date: Tue, 13 Jun 2023 19:13:09 -0700 [thread overview]
Message-ID: <20230614021312.34085-3-vishal.moola@gmail.com> (raw)
In-Reply-To: <20230614021312.34085-1-vishal.moola@gmail.com>
Introduce folio_migratetype() as a folio equivalent for
get_pageblock_migratetype(). This function intends to return the
migratetype the folio is located in, hence the name choice.
