While LFS is broken right now and is going to stay broken in 5.0,
there's interest in getting it fixed for 6.0. This is not trivial; the
LFS code has always had severe locking problems and what broke it this
time was the move to fine-grained SMP locking in the kernel.
(vmlocking2, for those who follow things closely.)

This may or may not be a viable proposition, and I may or may not be
able to find time to put into it, since I don't have much time total
and other things, like VFS-level cleanup, are really more important.

But it's not (yet) dead.

There's also another log-structured FS in development, called "nilfs",
which might be an alternative. It's also been suggested that doing a
fresh port of the Sprite LFS code might be better in the long run than
trying to fix what we have.
