gfs2: Extended attribute readahead optimization
Instead of submitting a READ_SYNC bio for the inode and a READA bio for
the inode's extended attributes through submit_bh, submit a single READ_SYNC
bio for both through submit_bio when possible. This can be more
efficient on some kinds of block devices.
