Pavel Emelyanov e651a6eba4 filemap: Get vma mnt_id early ... We have a, well, issue with how we calculate the vma's mnt_id. Right now get one via criu side file descriptor that it got by opening the /proc/pid/map_files/ link. The problem is that these descriptors are 'merged' or 'borrowed' by adjacent vmas from previous ones. Thus, getting the mnt_id value for each of them makes no sense -- these files are the same. So move this mnt_id getting earlier into vma parsing code. This brings a potential problem -- if we have two adjacent vmas mapping the same inode (dev:ino pair) but living in different mount namespaces -- this check would produce wrong result. "Wrong" from the perspective that on restore correct file would be opened from wrong namespace. I propose to live with it, since this is not worse than the --evasive-devices option, it's _very_ unlikely, but saves a lot of openeings. Note, that in case app switched mount namespace and then mapped some new library (with dlopen) things would work correctly -- new vmas will likely be not adjacent and for different dev:ino.
