Thanks, I didn't see that the first time around, but I'll be sure to look at
your new version. It sounds like you encountered the same problem I did
regarding block device handles: the devtmpfs inodes for the raw block device
handles are not the bdev inodes. I do think it's useful the alignment
attributes are accessible through the block device files, though.
