[Xen-devel] preempt_disable() imbalance in take_machine_down()? [linux-2.6.18-xen.hg]



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
