perf tools: Question about kmem and kernel symbol resolution

[Namhyung Kim]

Hi,

I'm looking kernel symbol mismatch issue, and found something in perf
kmem code.  The commit e727ca73f85d ("perf kmem: Resolve kernel
symbols again") added perf_session__create_kernel_maps() but I don't
know why.  Why did it miss the MMAP event?

I think if we create a kernel maps at report time, it might not match
to samples in a perf.data if it's recorded on a different kernel.
This is the main reason of the mismatch problem I'm currently chasing
IMHO.  What am I missing?

Thanks,
Namhyung
