David S. Miller ff06dffbc8 sparc: Add full proper error handling to strncpy_from_user(). ... Linus removed the end-of-address-space hackery from fs/namei.c:do_getname() so we really have to validate these edge conditions and cannot cheat any more (as x86 used to as well). Move to a common C implementation like x86 did. And if both src and dst are sufficiently aligned we'll do word at a time copies and checks as well. Signed-off-by: David S.
