Subject: setup_per_zone_pages_min(): take zone->lock instead of zone->lru_lock
X-Git-Tag: v2.6.27.10~2
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=42c17dd881fc3ebea2620fe879e18d84f141dd7f;p=pandora-kernel.git

setup_per_zone_pages_min(): take zone->lock instead of zone->lru_lock

commit 1125b4e3949949b44a7c80b619507c6f61d62911 upstream.

This replaces zone->lru_lock in setup_per_zone_pages_min() with zone->lock.
There seems to be no need for the lru_lock anymore, but there is a need for
zone->lock instead, because that function may call move_freepages() via
setup_zone_migrate_reserve().
