This includes a couple of fixes for lockless radix-tree bugs that we think the ScaleMP guys ran into (unconfirmed, but they do fix real bugs). The issue was just that some of the gang lookups were using the unsafe root->height rather than the lock-free-safe node->height fields. ftp://ftp.kernel.org/pub/linux/kernel/people/npiggin/patches/lockless/2.6.17-rc6/lockless.patch Thanks, Nick
