[PATCH bpf-next v2 0/2] Allow BPF TCP CCs to write app_limited

[Yixin Shen <bobankhshen@gmail.com>]

This series allow BPF TCP CCs to write app_limited of struct
tcp_sock. A built-in CC or one from a kernel module is already
able to write to app_limited of struct tcp_sock. Until now,
a BPF CC doesn't have write access to this member of struct
tcp_sock.

v2:
 - Merge the test of writing app_limited into the test of
   writing sk_pacing. (Martin KaFai Lau)
 
Yixin Shen (2):
  bpf: allow a TCP CC to write app_limited
  selftests/bpf: test a BPF CC writing app_limited
