Since the 5.x branch is mostly about SMP we'd like as much feedback as possible from users about possible locking problems as early as possible. To negate most of the performance impact I've also enabled WITNESS_SKIPSPIN. I've done this as we've been running WITNESS over the spinlock code for a while without incident and it goes a long way to making the performance problems of WITNESS much more bearable. Users who should be running current should know about turning WITNESS off for performance reasons. That said and done, WITNESS could/should be made into a tuneable, but we'll leave that as an excersize to those that want to disable it without a kernel recompile.
