    sys/kern             kern_mbuf.c 
  Log:
  Merge kern_mbuf.c:1.9.2.10 from RELENG_6 to RELENG_6_3:
  
    Call NET_LOCK_GIANT/NET_UNLOCK_GIANT around calls to protocol drain
    methods in mb_reclaim().  This is not an MFC, as debug.mpsafenet is
    not present in 7.x or 8.x.  In practice, this likely resulted in
    instability only on kernels with INVARIANTS, as the protocol drain
    paths are generally MPSAFE.
