csum_and_copy_..._user(): pass 0xffffffff instead of 0 as initial sum Preparation for the change of calling conventions; right now all callers pass 0 as initial sum. Passing 0xffffffff instead yields the values comparable mod 0xffff and guarantees that 0 will not be returned on success. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
