Subject: perf symbols: Factor out dso__load_vmlinux_path()
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=a19afe46412452fef89cc623873a8931b3685944;p=openwrt%2Fstaging%2Fblogic.git

perf symbols: Factor out dso__load_vmlinux_path()

So that we can call it directly from regression tests, and also
to reduce the size of dso__load_kernel_sym(), making it more
clear.
