Patch series "Optimize the fast path of mas_store()", v4. Add fast paths for mas_wr_append() and mas_wr_slot_store() respectively. The newly added fast path of mas_wr_append() is used in fork() and how much it benefits fork() depends on how many VMAs are duplicated. Thanks Liam for the review. This patch (of 4): Add tests for all cases of mas_wr_append() and mas_wr_slot_store().
