Functions libxl_tmem_freeze(), libxl_tmem_thaw(), libxl_tmem_set() and
libxl_tmem_shared_auth() located in libxl.c file return
ERROR_FAIL/ERROR_INVAL or internal error codes from libxc library
improve main_tmem_* return codes by returning EXIT_{SUCCESS/FAILURE}
accordingly to return codes of those functions.

Paulina,

These patches are all basically independent, right?

If you move as many of the patches which have suitable Acked /
Reviewed-by's to the front of the series on the next iteration, then a
committer can check in the ones which are ready to be checked in
immediately, and subsequent series (if any) can be much shorter.

Although at this point it's more complicated because they now also need
a release ack to be checked in. :-)

 -George
