Please define here the lock/unlock functions as well:
static inline int tdx_mng_key_lock(void)
{
int cpu = get_cpu();
cur_pkg = topology_physical_package_id(cpu);
mutex_lock(&tdx_mng_key_config_lock[cur_pkg]);
return cur_pkg;
}
static inline void tdx_mng_key_unlock(int cur_pkg)
{
mutex_unlock(&tdx_mng_key_config_lock[cur_pkg]);
put_cpu();
}
Thanks,
Paolo
