[PATCH] remove duplicating priority setting in try_to_free_p

From: minchan kim
Date: Sat Jan 26 2008 - 02:29:34 EST


shrink_zones in try_to_free_pages already set zone through
note_zone_scanning_priority.
So, setting prev_priority in try_to_free_pages is needless.

This patch is made by 2.6.24-rc8.
