The patch titled Subject: memcg: do not check for do_swap_account in mem_cgroup_{read,write,reset} has been removed from the -mm tree. Its filename was memcg-do-not-check-for-do_swap_account-in-mem_cgroup_readwritereset.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ From: Michal Hocko <mhocko@xxxxxxx> Subject: memcg: do not check for do_swap_account in mem_cgroup_{read,write,reset} Since 2d11085e ("memcg: do not create memsw files if swap accounting is disabled") memsw files are created only if memcg swap accounting is enabled so it doesn't make any sense to check for it explicitly in mem_cgroup_read(), mem_cgroup_write() and mem_cgroup_reset().
