Subject: [PATCH 17/18] perf tools: Set ksymbol dso as loaded on arrival
Date: Sun, 16 Feb 2020 20:30:04 +0100 [thread overview]
Message-ID: <20200216193005.144157-18-jolsa@kernel.org> (raw)
In-Reply-To: <20200216193005.144157-1-jolsa@kernel.org>
There's no special load action for ksymbol data on
map__load/dso__load action, where the kernel is getting
loaded. It only gets confused with kernel kallsyms/vmlinux
load for bpf object, which fails and could mess up with
the map.
Disabling any further load of the map for ksymbol related dso/map.
