[PATCH RESEND net-next 2/2] net-memcg: Remove redundant tcpmem_pressure
From: Abel Wu <hidden>
Date: 2023-07-11 12:43:17
Also in:
cgroups, linux-mm, lkml
Subsystem:
control group - memory resource controller (memcg), memory management, the rest · Maintainers:
Johannes Weiner, Michal Hocko, Roman Gushchin, Shakeel Butt, Andrew Morton, Linus Torvalds
As {socket,tcpmem}_pressure are only used in default/legacy mode
respectively, use socket_pressure instead of tcpmem_pressure in all
kinds of cgroup hierarchies.
