Kir Kolyshkin c4247302f7 criu: change the way -v works 
For most of the CLI tools I see, adding -v option increases their verbosity.

Currently, this is not the case for criu. Default verbosity is set it 2,
and using -v actually decreases the verbosity level to 1, so to increase
verbosity you need to use -vvv (or -v3). To me, this behavior is
quite counterintuitive.

This patch changes the way -v works (but retains -vNUM as it was). Now,
using -v increases verbosity by +1 from the default value (and e.g. -vvv
increases it by +3).

Surely, this changes user experience: for example someone who
was using -v (rather than -v1 or -v0) to silent warnings, will
now have verbosity increased. IMHO this is for the better.

CRIU (Checkpoint and Restore in Userspace)

An utility to checkpoint/restore tasks. Using this tool, you can freeze a running application (or part of it) and checkpoint it to a hard drive as a collection of files. You can then use the files to restore and run the application from the point it was frozen at. The distinctive feature of the CRIU project is that it is mainly implemented in user space.

The project home is at http://criu.org.
