[CRIU] [PATCH 0/4] Optional files.c cleanup

[Cyrill Gorcunov]

Hi Pavel,

while being poking tty c/r code I've had to play with files.c
code, so when being there I decided to clean it up a bit (from
my POV). Thus this series is absolutely optional, if you don't
like how it's done -- simply ignore it.
