[CRIU] [PATCH RFC 0/3] Allow postpone fdinfo callbacks

[Kirill Tkhai]

Allow callback to be postponed, if some file requests that
by returning FDO_REPEAT as retval.

If so, callbacks for such files will be executed once again
after the callbacks for all other files in list have finished.

Patches 1-2 are preparations, patch 3 implements the above.

Kirill Tkhai (3):
      files: Make states callbacks return named error
      files: Make .post_open methods return named retvals
      files: Allow postponed fdinfo callbacks
