svn commit: r271174 - head/sys/sys

[Robert Watson]

Author: rwatson

New Revision: 271174
URL: http://svnweb.freebsd.org/changeset/base/271174

Log:
  Clarify a diagnostic printf() in the mbuf code: M_EXT doesn't necessarily
  imply a cluster is attached; it could also refer to some other sort of
  external storage (e.g., an sf_buf).
