... Forum: The Linux Kernel Hackers' Guide . Re : Does memory area assigned by "vmalloc()" get swapped to disk? ... I am sure mlock() works fine..and I will also use sys_mlock() in my kernel code if I have to but the problem with it is that my kernel code becomes part of any user process as it is a Prefetching system and mlock() as seen from its implementation checks for the super user privileges suser(). ... I was thinking if the fixed size array (e.g. buffer[100]) gets swapped to disk. ...
