NAK. (I did write a better email explaining all the ins and outs of why this won't work and why 64-bit get_user isn't possible, but my editor crapped out and lost all that well written message; I don't fancy typing it all out again.) Nevertheless, int test_ptr(unsigned int **v, unsigned int **p) { return get_user(*v, p); } produces a warning, and you can't get away from that if you stick 64-bit support into get_user(). Sorry, 64-bit get_user() is a no-no. -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
