You shouldn't.

I need to do this because I must use mlock in my software, but I can't
use root or suser to start it. So mlock alwaays fail.

You should be using rlimits for this.

thanks,

So how to set rlimits ?
My program is in user mode and has to allocate about 128MB to 512MB of non swappable memory. Maybe I can change the rlimits rights into my kernel module ?
Do you know how to do this and where to find informations ?
