[LTP] Posix test case mmap/31-1 fails on Linux/eglibc

Hi all,

I run mmap/31-1 failed with ENOMEM on linux, with error message:
off: fffffffffffff000, len: fffffffffffff000
Test FAIL: expect EOVERFLOW but get other error: Cannot allocate memory

But compare to mmap/24-2, it mmap() the same length but pass. Its output:
available memory: 18446744073709551615
addr: 7f78c54fa000, len: ffffffffffffffff
addr: 7f78c54fa000, len: fffffffffffff000
Test Pass: mmap/24-2.c Get ENOMEM: Cannot allocate memory

So I suppose that mmap/31-1 may need update, but I don't know how to
make mmap() overflow as expect.
Any suggestion is appreciated.

Regards,
Kai
