Re: [Xen-devel] [PATCH][Linux] Fix access to xenstore hangs afterhotremove CPU

["Jan Beulich" <jbeulich@xxxxxxxxxx>]

Using __cpuinitdata (or __cpuinit) in #ifdef CONFIG_HOTPLUG_CPU sections
is pointless. Either remove the #ifdef-s (and mark evtchn_cpu_notify()
__cpuinit) or remove the __cpuinitdata. I think the former is the preferred
upstream approach.

Hi,

CPU hotplug doesn't support user-space event channels.

$ echo 0 > /sys/devices/system/cpu/cpu1/online
$ xenstore-ls
... hangs up ...

Attached patch fixes it.

Thanks,
Kouya
