Albeit I wonder whether we shouldn't turn shutting_down into a bool, as all that seems to be needed is "shutting_down != SHUTDOWN_INVALID" today. But this could be part of another patch. Juergen

Currently when the toolstack issues a reboot, it gets translated into a call to ctrl_alt_del(). But tying reboot to ctrl-alt-del means rebooting may fail if e.g. the user has masked the ctrl-alt-del.target under systemd. A previous attempt to fix this set the flag to force rebooting when ctrl_alt_del() is called. However, this doesn't give userspace the opportunity to block rebooting or even do any cleanup or syncing. Instead, call orderly_reboot() which will call the "reboot" command, giving userspace the opportunity to block it or perform the usual reboot process while being independent of the ctrl-alt-del behaviour. It also matches what happens in the shutdown case. Signed-off-by: Ross Lagerwall <ross.lagerwall@citrix.com> --- drivers/xen/manage.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
