Hi Yafang,

Many thanks for the detailed analysis. Seems it can work.

Hi John,

Could you pls. try the attached fix ? I have verified it in my test env.

I tested the patch on my environment where I found the issue with newer
kernels + older Perfetto. The patch does improve things so that's nice.

Thanks for the test. I don't have Perfetto in hand, so I haven't
verify Perfetto.

FWIW, perfetto is not android specific and can run on normal linux distro setup
(which I do but haven't noticed this breakage).

It's easy to download the latest release (including for android though I never
tried that) from github

	https://github.com/google/perfetto/releases

Kajetan might try to see if he can pick the latest version which IIUC contains
a workaround.

If this simple patch can be tweaked to make it work again against older
versions that'd be nice though.

HTH.


Cheers
