[CRIU] [PATCH v4 0/3] Save content of unmounted binfmt_misc

[Kirill Tkhai]

Umount does not remove binfmt_misc content. If it's mounted once again,
the same entries remain registered. But criu does not handle such cases.

This patch forces mounting of unmounted binfmt_misc on dump, and make it
restore in the right way. 

v2: Cleanup mounted binfmt_misc in case of dump failed.
    Use get_fd_mntid().
    Print more info in error case.
v3: Close dir before umounting.
v4: Do not save temporary mountpoint in image.
    Add fix 0/3
