Subject: [PATCH v4 0/4] sock: Improve condition on sockmem pressure 

Currently the memcg's status is also accounted into the socket's
memory pressure to alleviate the memcg's memstall. But there are
still cases that can be improved. Please check the patches for
detailed info.

v4:
  - Per Shakeel's suggestion, removed the patch that suppresses
    allocation under net-memcg pressure to avoid further keeping
    the senders waiting if SACKed segments get dropped from the
    OFO queue.

v3:
  - Fixed some coding style issues pointed out by Simon
  - Fold dependency into memcg pressure func to improve readability

v2:
  - Splited into several patches and modified commit log for
    better readability.
  - Make memcg's pressure consideration function-wide in
    __sk_mem_raise_allocated().

v1: https://lore.kernel.org/lkml/20230506085903.96133-1-wuyun.abel@bytedance.com/
v2: https://lore.kernel.org/lkml/20230522070122.6727-1-wuyun.abel@bytedance.com/
v3: https://lore.kernel.org/lkml/20230523094652.49411-1-wuyun.abel@bytedance.com/

Abel Wu (4):
  net-memcg: Fold dependency into memcg pressure cond
  sock: Always take memcg pressure into consideration
  sock: Fix misuse of sk_under_memory_pressure()
  sock: Remove redundant cond of memcg pressure
