[CRIU] [PATCH 0/2] zdtm: file-locks01 -- Fix device numbering on btrfs

[Cyrill Gorcunov]

It turned out that when running on btrfs we can't fetch the proer
number of device we're mounted on until mountinfo parsed.

avagin@ proposed to use /proc/@fd/fdinfo instead but it seems
at moment it's not yet merged into sock fedora kernel so i cherry
picked a few snipets from criu source code to zdtm itself.

Please take a look once time permit.
