Bart,

Are you going to send a patch to fix this or do you want me to do it ?

Hi Damien,

Thanks for having taken a look. Please help with verifying whether the 
following patch is sufficient to fix the reported warning: "[PATCH] 
tracing: Suppress sparse warnings triggered by is_signed_type()" 
(https://lore.kernel.org/all/20220717151047.19220-1-bvanassche@acm.org/).

Bart.

With the current Linus tree, I do not see this sparse warning. However, applying

That doesn't make sense to me. My patch reduces the number of sparse 
warnings that are reported.

I think that you are hitting a bug in sparse. See also 
https://lore.kernel.org/all/e91d351c-3c16-e48d-7e9d-9f096c4acbc9@debian.org/T/. 
I also see the above warnings if I use the sparse binary from Debian 
testing. I do not see these sparse warnings if I download the sparse 
source code and compile that source code myself.

Bart.

Good point. I was using Fedora 36 sparse package. Using sparse compiled from
source, I now see again the warnings without the patch and no warnings with the
patch applied. So the patch looks good. Are you going to send it as a fix for
6.0-rc1 ?

Cheers.

Hi Damien,

It is not clear to me why I have not yet received any feedback from 
Steven Rostedt on that patch. I will try to ping Steven off-list. If 
necessary I will repost that patch.

Best regards,

Bart.
