Some filesystems (such as /proc, /sys, and so on - basicaly, the "pseudo" file systems) are able to stand by themselves. Filesystems that read actual blocks of data off actual media will require the services of the block layer to do that. So if you've built a tiny embedded kernel that doesn't include the block layer, you can't read those sorts of filesystems....
