[PATCH v2 00/10] Clean ups for maple tree

[Peng Zhang <zhangpeng.00@bytedance.com>]

Some clean ups, mainly to make the code of maple tree more concise.
This patchset has passed the self-test.

0006-0009 - Make mas_wr_modify() and its subfunctions clearer. Make the
            store operation of maple tree more efficient in some cases.

Thanks Liam and Matthew.

Changes since v1:
 - Rework mtree_alloc_{range,rrange}() instead of removing it. [01/10]
 - Fix the arguments to __must_hold() instead of removing it. [03/10]
 - Keep the fast path. Expand the compact code. [04/10]
 - Drop "maple_tree: Wrap the replace operation with an inline
   function.". [v1 06/10]
 - Remove some comments. [07/10] [08/10]
 - Avoid modifying wr_mas->offset_end in mas_wr_modify(). [09/10]
 - Add a patch to relocate mas_empty_area_rev(). [10/10]
