Modified files:
sys/kern uipc_mbuf.c
sys/sys mbuf.h
Log:
Fix a bug in m_split(): the "m->m_ext.ext_size" field of an mbuf was being
set to zero. This field indicates the total space in the external buffer
and therefore should not be modified after the external buffer is added.
Add a comment warning that the mbufs returned by m_split() might be read-only.
Fix M_TRAILINGSPACE() to return zero if !M_WRITABLE(m).
