->writepage() is not needed at all (it does not even exist anymore :),
and only ->writepages() is used.

POHMELFS relies on VFS to handle that cases, it does not invent own stuff here.
Although there is kind of a path/name cache, it is very trivial and small.

I think I will extend its command structure to support checksum (i.e.
add 64bit field unused for now), all other protocol changes are supposed
to be on the highest level (like new commands), so it should not hurt others.

I have to think about locking (file locks on server, not POHMELFS internal
locking :) some more, but so far I do not see, how it can change the picture.

Another task is to move from slab allocation (kmalloc and friends) to
memory pools, like it was done for transaction destinations.

I do not plan serious changes in client (I frankly do not know, what
else I want there :), so, yes, I think that most of the client side is ready.
