Is there any way to specify the allocated NUMA node for the shared memory obtained with mmap?

Neither mbind nor set_mempolicy can do it, is there any other way to do it?

I tried mbind and set_mempolicy, neither of them succeeded in binding to the assigned numa node

The thread default policy also controls allocation of any pages for memory-mapped files mapped using the mmap(2) call with the MAP_PRIVATE flag and that are only read (loaded) from by the thread and of memory-mapped files mapped using the mmap(2) call with the MAP_SHARED flag, regardless of the access type.
