Hi,
This is v2 of patchset to add virDomainGetFSInfo API.
* changes in v1->v2: -[all] removed redundant NULL element at the last of returned info array -[3/5] make error messages in qemu_agent.c consistent with other commands -[4/5] added a test case for 2 items in info->devAliases -[5/5] added a pod document for virsh domfsinfo command (v1: http://www.redhat.com/archives/libvir-list/2014-October/msg00001.html )
* summary This series implements a new virDomainGetFSInfo API, that returns a list of mounted filesystems information in the guest, collected via the guest agent.
The returned info contains mountpoints and disk device alias named in libvirt, so we can know which mountpoints should be frozen by virDomainFSFreeze to take snapshots of a part of disks.

I reviewed the 'libvirt' specific changes - had a few comments and have made changes to my review branch as specified. As long as you're OK with those changes I will get these pushed.
Thanks for the review and fixups! And I apologize I¹ve missed some of your last comments. I¹ll send v3 patch including your fixups, and some changes according to Eric¹s comments (adding length of devAlias array, using @acl domain:fs_freeze). Thanks, Tomoki
I'm also hoping someone else (eblake?) can look at the remote_protocol.x changes to ensure they encompass everything they are supposed to. Also that the usage of QEMU_JOB_QUERY not _MODIFY for the GetFSInfo seems more appropriate and is in line with the various remote_protocol.x settings (@acl/@generate stuff settings).
I'll look at the python changes separately, although I think phrdina understands what needs to change there the best!
