btrfs-progs: mkfs: refactor add_file_items
There were two major problems with the function add_file_items: it was writing all files sector-by-sector, making compression impossible, and it was assuming that pread would never do a short read. Fix these problems, and create a new helper function read_and_write_extent. Signed-off-by: Mark Harmstone <[email protected]>
