[PATCH V2 0/3] xen: pvscsi: avoid race, support suspend/resume

From: Juergen Gross
Date: Tue Feb 17 2015 - 02:03:28 EST

In the pvscsi backend copy the frontend request to ensure it is not
changed by the frontend during processing it in the backend.

Support suspend/resume of the domain to be able to access a pvscsi
device n the frontend afterwards.

Changes in V2:
- changed scsiback_do_cmd_fn() as sugested by Jan Beulich
- added adaption of backend parameters in frontend after resuming

Juergen Gross (3):
xen: mark pvscsi frontend request consumed only after last read
xen: scsiback: add LUN of restored domain
xen: support suspend/resume in pvscsi frontend
