Again, you miss the point -- this RLIM_NLIMITS comes into criu source
code not from kernel headers but from libc headers. So even if I install
headers from latest vanilla kernel the program still see old value = 15.

Thus what I think we should do -- provide own reasource.h in include/asm-generic,
where define CR_RLIM_NLIMITS = 16 and use it instead. Also we will use

	BUILD_BUG_ON (CR_RLIM_NLIMITS < RLIM_NLIMITS);

thus if someday libc increas this value to 17 or something -- we will note
this immediately and update our code as well.

Sounds good?
