[PATCH 0/2] Documentation: maple_tree: Improve statements on reserved values

[Wei-Lin Chang]

Hi,

This is another version of [1], where I improved wording.

While using the maple tree and reading its documentation, I found a few
bits confusing, mainly about the reserved values. So here are some
changes hoping to make things clearer.

I am not familiar with the implementation, so if I got something wrong
please let me know.

While looking at the code I also found that although the doc claims the
normal API blocks reserved value stores, the code checks this using
xa_is_advanced(), which only blocks values up to 1026, not up to the max
maple tree reserved value 4094. For this part I am not sure whether the
code needs to be changed or we can also improve the doc.

Any feedback is appreciated, thanks!
