I am not able to see the sched_compat_yield entry under /proc/sys/kernel/. How to enable this propery in the kernel (so that I can tweak it for some debugging purpose) ?

Currently Available Entries:

root@test ~ >ls /proc/sys/kernel/sched_*

I am using "Linux 3.3.0 #19 PREEMPT Wed May 8 14:38:18 IST 2013 armv5tejl GNU/Linux".

You won't be able to enable it because it doesn't exist any more - it was removed over two years ago by this commit which is included in 2.6.39 and later kernels.

If you're interested in how you can figure things like that out yourself then the answer is that I used git log -S sched_compat_yield in a kernel checkout to look for commits which introduce or remove that string from the code.

thanks a lot for introducing me to "git log -S" – Lunar Mushrooms May 14 '13 at 14:27
