[Qemu-devel] [PATCH v5 0/2]: qemu-ga: Add the guest-suspend command

[Luiz Capitulino <lcapitulino@redhat.com>]

I've tried to address all review comments in this new version. The
two most important changes is that I've added the 'sleep' and 'hybrid'
modes back and now the guest is queried for suspend support (the way
I'm doing this is also worth reviewing).

This series depends on this patch from Michael:

 http://lists.gnu.org/archive/html/qemu-devel/2012-01/msg01382.html

and from a patch I've submitted to seabios to disable S3 advertise,
as S3 is broken in qemu today.

v5

o add 'sleep' and 'hybrid' modes back
o query for suspend support using pm-is-supported & manual check
o use _exit() [Daniel]
o reopen standard file-descriptors to /dev/null [Eric]
o make the SIGCHLD handler more portable by calling waitpid() in
  a loop, as not all unix versions will raise SIGCHLD multiple
  times if several children terminate at once (I don't even know
  if Linux does that)
