Patch series "mm: task_stack: Stack handling cleanups". These are some small cleanups for the fork code that was split off from Pasha:s dynamic stack patch series, they are generally nice on their own so let's propose them for merging. This patch (of 2): No need to do zero cached stack if memcg charge fails, so move the charging attempt before the memset operation.
