Subject: [PATCH V2 0/3] xen: pvscsi: avoid race, support suspend/resume
Date: Tue, 17 Feb 2015 08:02:46 +0100 [thread overview]
Message-ID: <1424156569-13642-1-git-send-email-jgross@suse.com> (raw)
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
