maple_tree: add test for mas_wr_modify() fast path
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().
