perf annotate: Automatically pick up vmlinux in the local directory
Right now kernel debug info does not get resolved by default, because we dont know where to look for the vmlinux. The -k option can be used for that - but if no option is given, pick up vmlinux files in the current directory - in case a kernel hacker runs profiling from the source directory that the kernel was built in. The real solution would be to embedd the location (and perhaps the date/timestamp) of the vmlinux file in /proc/kallsyms, so that tools can pick it up automatically.
