[Ocfs2-tools-devel] [PATCH 4/6] Fix filesize in create_file

[Goldwyn Rodrigues]

While creating a new file, the filesize is left at zero, even though
there is an extent in the file.
This fix is required because further extents added using
ocfs2_extend_allocation compute the offset based on current filesize.
