I found that after having set the default subvolume to something other than the root, and then mounting it without the -o subvol= option, then the subvolume name does *not* show in /proc/self/mountinfo; the same happens if a subvolume is mounted by -o subvolid= rather than -o subvol=. Is this a bug? This would seem to give the worst of both worlds in terms of actually knowing what the underlying filesystem path would end up looking like. -hpa -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
