[CRIU] [PATCH 0/2] C/R of mandatory mountpoints

[Dmitry Safonov]

Support mandatory mounted mountpoints with excluseive locks.
The patches set dumps content of mountpoint by remounting without
`mand` option (when tree is freezed).
So, the only possible mess is when _out of tree process_ will try
to access file on dumping stage. But, I guess, that's what
one can expect with --file-locks option.
