Subject: [PATCH bpf-next v12 0/2] selftests/bpf: Optimize kallsyms cache
Date: Thu, 7 Sep 2023 09:59:12 +0800 [thread overview]
Message-ID: <tencent_FA47B711AB0DEC843EB3362E6355505ED509@qq.com> (raw)
From: Rong Tao <rongtao@cestc.cn>
We need to optimize the kallsyms cache, including optimizations for the
number of symbols limit, and, some test cases add new kernel symbols
(such as testmods) and we need to refresh kallsyms (reload or refresh).
