* Have m_pulldown() use the new M_WRITABLE() macro in order to determine
whether the given ext_buf is shared. * Have the sf_bufs be setup with the mbuf subsystem using MEXTADD() with the two new arguments. Note: m_pulldown() is somewhat crotchy; the added comment explains the situation. Reviewed by: jlemon
