Subject: preempt_disable() imbalance in take_machine_down()? [linux-2.6.18-xen.hg]
Date: Tue, 05 Apr 2011 15:59:13 +0200	[thread overview]
Message-ID: <4D9B2031.5080100@redhat.com> (raw)

Hi,

please excuse the lame question.

Looking at take_machine_down() and __xen_suspend() in 
"drivers/xen/core/machine_reboot.c", assuming "fast_suspend" is false, 
it seems that after the loop in take_machine_down() completes, 
preempt_enable() is never called. Is this intentional? If so, how/why 
does it work?

Thank you very much,
Laszlo Ersek
