Oh no, you only have one allocator, and you have the filesystem do it, with
per-sb methods. Why is this better than having the VFS do it? Does this
imply you might have different sized inodes with different mounts of the same
filesystem?
The per-fs cost with my variant is: 4-8 bytes per filesystem, period. No
methods needed, and the object management code doesn't get replicated through
all the filesystems.
Also, having the inode point at itself is a little, hmm, 'what's wrong with
this picture', don't you think?
