Module Name:    src
Committed By:   bouyer

Modified Files:
        src/sys/kern: uipc_mbuf.c

Log Message:
m_split0(): If the newly allocated mbuf holds only the header,
don't forget to set m_len to 0. Otherwise whatever will compute the size
of this chain (including s_split() itself if called again on this chain)
will get it wrong, leading to various issues.

Bug exposed by the NFS server code with linux clients using TCP mounts.
