ltp: diotest4: Let kernel pick an address when calling mmap
Error: diotest4 10 TBROK : diotest4.c:368: can't mmap file: Invalid argument diotest4 11 TBROK : diotest4.c:368: Remaining cases broken This is because the manually specified addr from mmap is invalid. We should let kernel itself pick an addrress. Signed-off-by: Hongzhi.Song <hongzhi.song@windriver.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
