X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=34b100605cb7e201d5c4e39f54d0e11caa950733;p=openwrt%2Fstaging%2Fblogic.git 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.
