Subject: vmscan: move ClearPageActive from move_active_pages() to shrink_active_list()
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=5205e56eeab04ce02f8bb6b47d1569b216bc0b6a;p=openwrt%2Fstaging%2Fblogic.git

vmscan: move ClearPageActive from move_active_pages() to shrink_active_list()

The move_active_pages_to_lru() function is called under irq disabled and
ClearPageActive() doesn't need irq disabling.

Then, this patch move it into shrink_active_list().
