Subject: [PATCH v2 04/28] fs: Rename AS_THP_SUPPORT and mapping_thp_support
Date: Mon,  8 Nov 2021 04:05:27 +0000	[thread overview]
Message-ID: <20211108040551.1942823-5-willy@infradead.org> (raw)
In-Reply-To: <20211108040551.1942823-1-willy@infradead.org>

These are now indicators of multi-page folio support, not THP support.
