If TLD_FREE_DATA_ON_THREAD_EXIT is not enabled in a translation unit that calls __tld_create_key() first, another translation unit that enables it will not get the auto cleanup feature as pthread key is only created once when allocation metadata. Fix it by always try to create the pthread key when __tld_create_key() is called. Also improve the documentation: - Discourage user from using different options in different translation units - Specify calling tld_free() before thread exit as undefined behavior Signed-off-by: Amery Hung <ameryhung@gmail.com> Link: https://lore.kernel.org/r/20260331213555.1993883-6-ameryhung@gmail.com Signed-off-by: Alexei Starovoitov <ast@kernel.org> |
