Is this patch perhaps intended for the util-linux project? According to 
the README file of that project util-linux patches should be sent to 
util-linux at vger.kernel.org.

Additionally, shouldn't Damien Le Moal have been CC'ed for this patch?

What code in configure.ac defines HAVE_BLKZONED_H? Would the following 
code have been sufficient: AC_CHECK_HEADER([linux/blkzoned.h]) ? See
