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.
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).
@generate is correct, since both, client and server implementations are
provided.
@acl looks consistent to the rest. Correct, for querying domain info you
need to have read permission and that's it.
And yes, the job should be _QUERY since we are querying info, not
modifying domain in any way.
However, for some reason I see this build error after 2/5:
