I am applying real time patch to the linux vanilla kernel. I osadl website recommends kernel version 2.6.33 but it was written in 2010 https://www.osadl.org/Latest-Stable-Realtime.latest-stable-realtime-linux.0.html
As I have read linux kernel 3.x have better preemption by default. Which one is better for real time application? Should I use kernel 3.x with rt patch?
