Similarly copy_from_user() returns an error if the destination generates a fault. In other words: drivers/char/mem.c requires that the architecture's copy_*_user() functions correctly handle faults on either the source or dest of the copy. - To unsubscribe from this list: send the line "unsubscribe linux-ia64" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.htmlReceived on Fri Oct 17 18:53:09 2003
