Hi,

This patch serie adds support for explicit control of zone transitions.

To test it, one can use an updated blkzone version that is available
here:

  https://github.com/MatiasBjorling/util-linux.git zonemgmt

blkzone can be compiled with:

  ./autogen.sh
  ./configure
  make blkzone

After that, the binary is available in the compile directory.

Regards,
Matias
