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.
