I tested ltp mbind01 case and found the case10 failed. In case10, the expect errno is EFAULT.
In mbind manual, it says "EFAULT Part or all of the memory range specified by nodemask and maxnode points outside your accessible address space. " So the case should use invalid "nodemask" instead of invalid "p" to test.
