Subject: f2fs: fix to tag FIEMAP_EXTENT_MERGED in f2fs_fiemap()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=0953fe864c4d05f5a5cde626a630a76918cf4f9c;p=linux.git

f2fs: fix to tag FIEMAP_EXTENT_MERGED in f2fs_fiemap()

f2fs does not natively support extents in metadata, 'extent' in f2fs
is used as a virtual concept, so in f2fs_fiemap() interface, it needs
to tag FIEMAP_EXTENT_MERGED flag to indicated the extent status is a
result of merging.
