Modified files:
sys/kern subr_mbuf.c
sys/sys mbuf.h
Log:
Add the M_FREELIST flag, which is used to detect whenever a
double free of a mbuf occurs and cause an immediate panic, rather
than allowing free list corruption to occur.
This code is trapped under INVARIANTS, so it should not cause any
change in default performance.
