Hi All

For this patch, vfsv0 and vfsv1 should have different limit when tesing 
ERANGE error.

vfsv0: 2^42 bytes
vfsv11: 2^63 -1 bytes (Also sent a patch to man-pages) after kernel 4.1[1].

         }

         if (access(USRPATH, F_OK) == -1)


Also for old kernel ie centos7 without patch[2], we can't meet ERANGE 
error for vfsv1 format because it doesn't use block shift.
