From a25a4e1a5d5dc0f97dddbca44e695c532d8228c1 Mon Sep 17 00:00:00 2001 From: Zheng Liu Date: Mon, 18 Feb 2013 00:28:04 -0500 Subject: ext4: let ext4_ext_map_blocks return EXT4_MAP_UNWRITTEN flag This commit lets ext4_ext_map_blocks return EXT4_MAP_UNWRITTEN flag because in later commit ext4_map_blocks needs to use this flag to determine the extent status.
