Subject: [PATCH] iomap: Export iomap_page_create and iomap_set_range_uptodate
Date: Tue, 10 Dec 2019 11:29:16 +0100	[thread overview]
Message-ID: <20191210102916.842-1-agruenba@redhat.com> (raw)

These two functions are needed by filesystems for converting inline
("stuffed") inodes into non-inline inodes.
