Andrew Shewmaker 1640879afe mm: reinititalise user and admin reserves if memory is added or removed ... Alter the admin and user reserves of the previous patches in this series when memory is added or removed. If memory is added and the reserves have been eliminated or increased above the default max, then we'll trust the admin. If memory is removed and there isn't enough free memory, then we need to reset the reserves. Otherwise keep the reserve set by the admin. The reserve reset code is the same as the reserve initialization code. I tested hot addition and removal by triggering it via sysfs. The reserves shrunk when they were set high and memory was removed. They were reset higher when memory was added again.
