           Summary: Wno-unused-function used by mistake?
           Product: Base System
           Version: 11.0-CURRENT
          Hardware: Any
               URL: http://svnweb.freebsd.org/base/head/sys/conf/kern.mk?v

Hi,

r261991 by dim@ added -Wno-unused-function to kernel compile flags via
CWARNEXTRA.  Also MFCd to 10-STABLE by r263763 and 9-STABLE by r263509

This looks wrong in context and from the preceding comment.  I think the intent
may have been to only *not fail* in case of the warning
(-Wno-error-unused-function).  But instead, this type of was disabled
completely from being shown.

I thought this ought to be double-checked (or otherwise fix the comment if it
is intentional).  Just in case one day, an unused function is introduced and
nobody ever sees the warning...

Thanks!!
