Subject: mm/page_alloc.c: change sysctl_lower_zone_reserve_ratio to sysctl_lowmem_reserve_ratio in comments
We use sysctl_lowmem_reserve_ratio rather than
sysctl_lower_zone_reserve_ratio to determine how aggressive the kernel is
in defending lowmem from the possibility of being captured into pinned
user memory. To avoid misleading, correct it in some comments.
