:Hmm, why bzero at all if you are just going to free it? Why not move the bzero

He is invalidating the structure to catch references to deleted sbufs.
(see assert_sbuf_integrity() calls).
Josef, I take back my last request... I think there's another bug.
Your vmstat -m output showed that both the sbuf pool and the VFS cache
pool were blown up. The fix I just made will probably only solve the
sbuf pool issue. If you still want to test it, observe both pools
in the vmstat -m output carefully!
