Subject: memcg: convert threshold to bytes

From: Shaohua Li <[email protected]>

commit 424cdc14138088ada1b0e407a2195b2783c6e5ef upstream.

page_counter_memparse() returns pages for the threshold, while mem_cgroup_usage() returns bytes for memory usage. Convert the threshold to bytes.

Fixes 3e32cb2e0a12b6915 ("memcg: rename cgroup_event to mem_cgroup_event").
