Nope. Lowmem rezerve is a measure to protect from allocations targetting
higher zones (have a look at setup_per_zone_lowmem_reserve). The value
for each zone depends on the amount of memory managed by the zone
and the ratio which can be tuned from the userspace. min_free_kbytes
controls reclaim watermarks.
