The fact that the mouse stops working is indicative that this patch doesn't actually fix the problem, it's just pushing it around in the kernel - sooner or later something *else* is going to go pear-shaped on the null *mm. The right fix is to figure out why mm is bogus and fix that issue. --==_Exmh_1115233903_4721P Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.1 (GNU/Linux) Comment: Exmh version 2.5 07/13/2001 iD8DBQFCeR5vcC3lWbTT17ARAuRfAJ93dCobGEdoRCQIPmrPCRJec9G1CwCfSmXt W5Xn6I8/udXBFSxJwFM4VqQ= =4ppE -----END PGP SIGNATURE----- --==_Exmh_1115233903_4721P-- - 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/
