does really noone have an answer for me?? i'm having the hardest time to find a work-around for it.
is there no way to tell the kernel, that a certain mapping must not be removed, no matter what (except of course an explicit call to sys_unmap, of course)? - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
