The patch titled
Subject: net: tcp_memcontrol: simplify linkage between socket and page counter
has been removed from the -mm tree. Its filename was
net-tcp_memcontrol-simplify-linkage-between-socket-and-page-counter.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Johannes Weiner <hannes@xxxxxxxxxxx>
Subject: net: tcp_memcontrol: simplify linkage between socket and page counter
There won't be any separate counters for socket memory consumed by
protocols other than TCP in the future. Remove the indirection and link
sockets directly to their owning memory cgroup.
