AFAICT the patch applied cleanly. There was some bizarre interplay in 
stable kernels prior to < 6.1 as reported here:

https://lore.kernel.org/all/dcb9997a-2e8a-5eb2-7a34-f8af418d4bf1@xxxxxxxxx/
https://lore.kernel.org/all/6a577578-8adb-aa70-1bf8-b1a4573152cf@xxxxxxxxx/

Does this make sense to you that on 6.1 which does have Ian's commit 
00facc760903be6675870c2749e2cd72140e396e ("perf jevents: Switch build to 
use jevents.py") that we would still get this build error somehow?

Thanks
