Modified Files:
src/sys/nfs: nfs_srvsocket.c
Log Message:
When partitioning a mbuf chain with m_split() the last mbuf of the returned
tail chain is not necessarily the same as the last mbuf of the initial chain.
Always set "slp->ns_rawend" to the last mbuf of the tail chain to prevent
mbuf leaks and corruption.
