[CRIU] [PATCH 0/4] Improve cmdline error handling

[Kir Kolyshkin]

This small series makes a number of improvements on how criu reports
on invalid command line errors. As a result, it is more easier to
comprehend out what exactly is wrong with the command.

Kir Kolyshkin (4):
  main(): don't dupe open_image_dir() error message
  criu: unify/improve bad argument messages
  criu: unify invalid usage error messages
  criu: don't show long usage in case of error
