It means the original fix was applied to CURRENT (what is also known as
HEAD), and then "backported" to RELENG_7 (what you would call FreeBSD
7.x-STABLE) on 2008/03/20.  "MFC" stands for "Merge From CURRENT".

You can confirm this by looking at cvsweb for the file in question:

http://www.freebsd.org/cgi/cvsweb.cgi/src/sys/dev/usb/ums.c

The change for HEAD/CURRENT was made in Revision 1.98 (date = Mar 12)
The MFC to RELENG_7 was made in Revision 1.96.2.1 (date = Mar 20)

If you csup your src tree (use /usr/share/examples/cvsup/stable-supfile)
the patched code will be downloaded and used.  You'll have to rebuild
world to get the changes, of course.  See the FreeBSD Handbook for doing
a csup as well as for rebuilding world.
