vkernel bug - "mfree: m->m_nextpkt != NULL"


From: Matthew Dillon <dillon@xxxxxxxxxxxxxxxxxxxx>

    I get this in the vkernel, usually when I exhaust the mbuf objcache.

    The bug is the "mfree: m->m_nextpkt != NULL" message, not the mbuf
    exhaustion (while testing async write BIOs w/NFS I didn't slap any
    limits on how many it tried to run in parallel) <GRIN>.
