commit 6e9c08674f7055f843113ddf9e181ec05ca764fd Author: Matthew Dillon <dillon@apollo.backplane.com> Date: Sun Jul 17 23:45:11 2011 -0700 kernel - Additional fixes for vm_prefault issue * Fix a case where map->timestamp was being tested without holding the map lock, which can race. We now relock the map prior to testing map->timestamp. * Fix a case where map->timestamp was being adjusted with the map lock released.
