Date: Tue, 29 Aug 2017 16:29:40 +0200 From: Andreas Gruenbacher <agruenba@...hat.com> To: linux-fsdevel@...r.kernel.org Cc: linux-ext4@...r.kernel.org, linux-xfs@...r.kernel.org, Jan Kara <jack@...e.cz>, Christoph Hellwig <hch@....de>, Andreas Gruenbacher <agruenba@...hat.com> Subject: [PATCH 2/4] iomap: Add IOMAP_F_DATA_INLINE flag Add a new IOMAP_F_DATA_INLINE flag to indicate that a mapping is in a disk area that contains data as well as metadata. In iomap_fiemap, map this flag to FIEMAP_EXTENT_DATA_INLINE.
