@Wei, @Petr, did you get it to work after trying the above diff?
Which kernel did you use?

Unfortunately, neither of these methods (including Wei's method) works
properly on my kernel-6.19.0-rc2 platform.

And no matter what method I try, the child process still cannot switch
to the new TLS. More details see I posted in the pre-thread.
