Modified files:
sys/kern kern_mbuf.c
sys/sys mbuf.h
sys/vm uma.h uma_core.c
Log:
Fix for problems that occur when all mbuf clusters migrate to the mbuf packet
zone. Cluster allocations fail when this happens. Also processes that may have
blocked on cluster allocations will never be woken up. Thanks to rwatson for
an overview of the issue and pointers to the mbuma paper and his tool to dump
out UMA zones.
