Hi,
There is a patch to fix vma03 test case,the below information is
detail it:
the offset the parameter of mmap2() doesn't align the page
size,but,this parameter
allow must be a multiple of the page size as returned by
sysconf(_SC_PAGE_SIZE).
meanwhile offset * 4096 must be a multiple of the system page
size,so modify
the input param of offset pgoff = (ULONG_MAX - 1)&(~((pgsz-1)>>12));
Regards,
Apollo
