Subject: Re: [PATCH] tools/sched_ext: Improve BPF verifier arena detection workaround

Thanks for catching this.To be honest, this change was primarily a result of my attempt to comb through and reorganize the code logic. I mistakenly thought it was applicable here and did not perform a complete runtime test for this specific modification.I apologize for the breakage. I will revert/fix this logic in the next revision to ensure the scheduler loads correctly.
