[CRIU] [PATCH 0/3] Add support to flock&posix file locks' dump/restore

[Andrey Wagin]

Hello,

Did you test this patches? I guess the answer is yes, so pls add your tests
in zdtm.
zdtm is a set of unit tests for crtools. All developers executes "make
test" for checking that nothing broken.

Thanks.
