Hi,
Just a heads up that there is a header file mismatch between the tools
and kernel includes in 5.9 rc8. Building from the src.rpm I get this
error.
Warning: Kernel ABI header at 'tools/include/uapi/linux/perf_event.h'
differs from latest version at 'include/uapi/linux/perf_event.h'
The difference between the two files is a single line:
< #define PERF_MEM_SNOOPX_SHIFT 38
---
> #define PERF_MEM_SNOOPX_SHIFT 37
$ diff -U5 -p tools/include/uapi/linux/perf_event.h include/uapi/linux/perf_event.h

I'm not sure which is the correct version, but once I know I can fix
this with a patch (the above will work), but is there a better way? I
realize that the Fedora kernel no longer builds tools directly, but
could you make this change there?
Thanks.
