Subject: [PATCH v2 bpf 0/2] bpf: net: Fixes in sk_user_data of reuseport_array

This set fixes two issues on sk_user_data when a sk is added to
a reuseport_array.

The first patch is to avoid the sk_user_data being copied
to a cloned sk.  The second patch avoids doing bpf_sk_reuseport_detach()
on sk_user_data that is not managed by reuseport_array.

Since the changes are mostly related to bpf reuseport_array, so it is
currently tagged as bpf fixes.

v2:
- Avoid ~3UL (Andrii)

Martin KaFai Lau (2):
  bpf: net: Avoid copying sk_user_data of reuseport_array during
    sk_clone
  bpf: net: Avoid incorrect bpf_sk_reuseport_detach call
