Right, there's a consensus that the fs includes have to fixed and that it
should be in 2.5.lownum. The precise plan isn't fully evolved yet ;)

See fsdevel for the thread, 3-4 months ago. IIRC, the favored idea (Linus's)
was to make the generic struct inode part of the fs-specific inode instead of
the other way around, which resolves the question of how the compiler
calculates the size/layout of an inode.

This is going to be a pervasive change that someone has to do all in one
day, so it remains to be seen when/if that is actually going to happen.

It's also going to break every out-of-tree filesystem.
