Really stable?  It improves performance, which is nice.  But every patch
which goes into the kernel fixes a bug, improves clarity, improves
performance or adds a feature.  I've now seen all four cases get CC'd
into stable.

Including some of mine explicitly not marked stable which get swept up
by enthusiastic stable maintainers :(

Is now there *any* patch short of a major rewrite which shouldn't get
cc: stable?

Cheers,
Rusty.
