From 9ca250a5137f3df7ffac58b49660beadd5926ace Mon Sep 17 00:00:00 2001 From: Andreas Gruenbacher Date: Sun, 1 Oct 2017 17:56:54 -0400 Subject: 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.
