mm: rename page_counter's count/limit into usage/max
This patch renames struct page_counter fields:
count -> usage
limit -> max
and the corresponding functions:
page_counter_limit() -> page_counter_set_max()
mem_cgroup_get_limit() -> mem_cgroup_get_max()
mem_cgroup_resize_limit() -> mem_cgroup_resize_max()
memcg_update_kmem_limit() -> memcg_update_kmem_max()
memcg_update_tcp_limit() -> memcg_update_tcp_max()
The idea behind this renaming is to have the direct matching
between memory cgroup knobs (low, high, max) and page_counters API.
This is pure renaming, this patch doesn't bring any functional change.
