RTOS & SeLinux kernel modules...

[fu11m00n]

I started my project 6 yrs ago and yet it appears the more I know the more I don't know.
I understand the Slackware/Porteus ecosystem but alas I have not made peace with kernels.

I'm interested in adding realtime and SeLinux support to my project.
Unfortunately, I'm not sure where to start.

I could be wrong... but if the kernel was generic upstream it would be easier to add kernel modules.
In any case... I am curious to know what the process is for adding kernel support.

Thanks in advance for any information on this issue to move my project forward.
