      criu: Version 2.4 · 9a97e0ca
      Pavel Emelyanov authored 
      This time we have a bunch of new features, such as more
cgroup stuff, AutoFS, coredump out of images, etc.

Virtuozzo guys have released vz7-rtm, and fixed a lot
of bugs in criu while doing it :)

Plus some ancient stuff removed.

      criu: almost fix building on Alpine Linux · 09a2afe0
      Adrian Reber authored 
      It seems that the different libc (musl) which Alpine Linux uses produces
different errors than the usual glibc. This patch fixes most include
errors. Two errors are not yet resolved on Alpine Linux's libc (musl):

 * proc_parse.c: In function 'parse_posix_timers':
   proc_parse.c:2125:34: error: 'SIGEV_THREAD_ID' undeclared (first use in this function)
        timer->spt.it_sigev_notify = SIGEV_THREAD_ID;

   proc_parse.c:2125:34: note: each undeclared identifier is reported only once for each function it appears in

   Seems difficult to fix as including <linux/signal.h>, which provides
   this #define, generates more different error messages related to
   time.h and linux/time.h collisions. It is not yet clear if additional
   guards would help in the header files.

 * fsnotify.c: In function 'open_by_handle':
   fsnotify.c:107:9: error: implicit declaration of function 'open_by_handle_at' [-Werror=implicit-function-declaration]
     return open_by_handle_at(fd, arg, O_PATH);

   The function open_by_handle_at() is not provided by Alpine Linux's
   libc (musl).

This patch resolves the following errors/warnings and has been tested on
RHEL7(x86_64/powerpc64le) and Fedora 24:

      Hopefully this would/will trigger more of these types of bugs; I took this
list straight from Adrian's report.

      cgroup: only write one device entry at a time · 0e83397d
      Tycho Andersen authored 
      We seem to have some reports of:

Error (cgroup.c:1193): cg: Failed writing c *:* m
b *:* m
c 1:3 rwm
c 1:5 rwm
c 1:7 rwm
c 5:0 rwm
c 5:2 rwm
c 1:8 rwm
c 1:9 rwm
c 136:* rwm
c 10:229 rwm to devices//lxc/c7/devices.allow: Argument list too long

so let's try and write these lines one by one, instead of simply advancing
the pointer along in the string. It's probably cleaner this way anyway :)
