Subject: Fix btrfs-convert's large file support.
X-Git-Tag: upstream/0.20.rc1~270
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=fb0a5d3766ac007dc316dd3a9cf737192f80d91f;p=platform%2Fupstream%2Fbtrfs-progs.git

Fix btrfs-convert's large file support.

This patch add ext2_inode.i_size_high into account when calculating regular
file's size in btrfs-convert,  which makes it deal with large files bigger than
4GB properly.
