svn commit: r267291 - head/sys/libkern

[John Baldwin]

Author: jhb
Date: Mon Jun  9 19:27:47 2014
New Revision: 267291
URL: http://svnweb.freebsd.org/changeset/base/267291

Log:
  Use strcasecmp() instead of strcmp() when checking user-supplied encoding
  names so that encoding names are treated as case-insensitive.  This allows
  the use of 'utf-8' instead of 'UTF-8' for example and matches the behavior
  of iconv(1).
