I have (naïvly) try this: vaddr=vmalloc(len); do_mmap(file ,kvaddr ,len ,PROT_READ|PROT_WRITE ,MAP_FIXED|MAP_PRIVATE ,0); Here, do_mmap check if the addresse match inside current process and return me -ENOMEM. Are there others functions which i could use to associate this file and a vmalloc'ed space ? j. -- Jérôme de Vivie - 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/ | ||||||||||||
