net-memcg: Pass struct sock to mem_cgroup_sk_under_memory_pressure().

2025-08-20T02:20:59+00:00

We will store a flag in the lowest bit of sk->sk_memcg. Then, we cannot pass the raw pointer to mem_cgroup_under_socket_pressure(). Let's pass struct sock to it and rename the function to match other functions starting with mem_cgroup_sk_. Note that the helper is moved to sock.h to use mem_cgroup_from_sk().

net-memcg: Introduce mem_cgroup_sk_enabled().

2025-08-20T02:20:59+00:00

The socket memcg feature is enabled by a static key and only works for non-root cgroup. We check both conditions in many places. Let's factorise it as a helper function.
