It depends on what you mean by "verify". I looked at the Linux kernel source code and checked that the "posix-cpu-timers: Unbreak timer rearming" patch is in 4.19.19 (but not 4.19.18) and in 4.20.6 (but not 4.20.5). I did not test Emacs's CPU profiler on these kernels, as I don't have them installed. I expect to upgrade soon to 4.20.6 (whenever Fedora 29 release does - 4.20.6 was submitted for testing a couple of days ago) and plan to give it a try then.
