Hi Pavel,
thanks for providing a test case. I tried it with your prlimit patch, but it fails for some architectures like or1k, x86 and m68k.
Do you have an idea why?
best regards Waldemar

Add tst-rlimit test to check setrlimit/getrlimit/prlimit and setrlimit64/getrlimit64/prlimit64 functions. Add tst-rlimit64 to check the 64-bit offset variant.
