Re: [libvirt] [PATCH v5 1/5] Introduce virDomainFSFreeze() and virDomainFSThaw() public API

These will freeze and thaw filesystems within guest. The APIs take @disks and @ndisks parameters to specify disks to be frozen or thawed. The parameters can be NULL and 0, then the all mounted filesystes are frozen or thawed. If some disks are frozen multiple times, they are not thawed until requested to be thawed as many times as freeze request. @flags parameter, which are currently not used, is for future extensions.
