[PATCH] klist: fix klist to have the same klist_add semantics as list…

…_head at the moment, the list_head semantics are list_add(node, head) whereas current klist semantics are klist_add(head, node) This is bound to cause confusion, and since klist is the newcomer, it should follow the list_head semantics. I also added missing include guards to klist.h Signed-off-by: James Bottomley <[email protected]> Signed-off-by: Greg Kroah-Hartman <[email protected]>
