[PATCH bpf-next v10 0/2] selftests/bpf: Optimize kallsyms cache

Posted by Rong Tao 2 years, 3 months ago

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).

Rong Tao (2):
  selftests/bpf: trace_helpers.c: optimize kallsyms cache
  selftests/bpf: trace_helpers.c: Add a global ksyms initialization
    mutex
