[Xen-devel] [PATCH 0/2] xenbus: Fix S3 frontend resume when xenstored is not running



Hi,

This patch series fixes the S3 resume of dom0 or a Xenstore stub domain
running a frontend over xenbus (xen-netfront in my use case).

As device resume is happening before process resume, the xenbus frontend
resume is hanging if xenstored is not running, thus causing a deadlock.
This patch series is fixing that issue by bypassing the xenbus frontend
resume when we are running in dom0 or a Xenstore stub domain.

Aurelien Chartier (2):
  xenbus: save xenstore local status for later use
  xenbus: bypass xenbus frontend resume if xenstored is not running
