Re: [Libguestfs] [PATCH libguestfs] daemon: lvm: Do reverse device name translation on pvs_full device fields

This is another failure, this time in virt-diff (see attachment for full build log). virt-diff works by opening two handles to different disk images and the comparing the filesystems in each. When we stat files in the two handles: handle 'g1' returns st_dev = 2065 [8:17, /dev/sdb1] handle 'g2' returns st_dev = 2049 [8:1, /dev/sda1] (for files under the /boot mountpoint). Indeed looking at the log we can see that (as in the previous case) /dev/sda and /dev/sdb are swapped. Reverse device name translation has never even considered the case of rewriting st_dev numbers, but I guess we'll have to do that now. I wonder why this has suddenly started happening. Kernel update? I cannot reproduce it locally.
