Anything that need modification of a normal non-shared fs is utterly
broken and you'll get a clear NAK, so the propsal before is a good
one. There's a couple more issues like the still weird prototypes,
e.g. and i_ino might not be enoug to uniquely identify an inode
on serveral filesystems that use 64-bit inode inode numbers on 32-bit
systems. Also making the ops vector global is just a bad idea.
There is nothing making this sort of caching inherently global.
