[PATCH] f2fs: fix to tag FIEMAP_EXTENT_MERGED in f2fs_fiemap()

From: Chao Yu
Date: Mon Dec 14 2020 - 04:22:40 EST


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.
