Checkpatch fixes --- From 5f089c0b2a57ff6c08710ac9698d65aede06079f Mon Sep 17 00:00:00 2001 From: Michal Hocko <mhocko@xxxxxxx> Date: Thu, 4 Jul 2013 17:15:54 +0200 Subject: [PATCH] mm: Honor min_free_kbytes set by user min_free_kbytes is updated during memory hotplug (by init_per_zone_wmark_min) currently which is right thing to do in most cases but this could be unexpected if admin increased the value to prevent from allocation failures and the new min_free_kbytes would be decreased as a result of memory hotadd. This patch saves the user defined value and allows updating min_free_kbytes only if it is higher than the saved one. A warning is printed when the new value is ignored.

Thank you. I have similar patch and I have been bothered long time to refine and post it. Yes, current logic is not memory hotplug aware and could be dangerous.
