[PATCH V5 0/2] xenbus: Fix S3 frontend resume when xenstored is not running

[Aurelien Chartier <aurelien.chartier@citrix.com>]

Hi,

This patch series fixes the S3 resume of a domain running xenstored and 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 deferring the xenbus frontend
resume when we are running xenstored in that same domain.

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