Subject: lib/radix-tree: remove unused argument of insert_entries
Date: Sat, 25 Jun 2022 21:53:24 +0800
insert_entries() doesn't use the 'bool replace' argument, and the function
is only used locally, remove the argument.
The historical context of the unused argument is as follow:
2: commit <3a08cd52c37c79> (radix tree: Remove multiorder support)
Remove the code related to macro CONFIG_RADIX_TREE_MULTIORDER
to convert to the xArray.
Without the macro, there is no need to retain the argument.
1: commit <175542f575723e> (radix-tree: add radix_tree_join)
Add insert_entries(..., bool replace) function, depending on the
macro CONFIG_RADIX_TREE_MULTIORDER definition, the implementation
is different. Notice that the implementation without the macro doesn't
use the argument.
[Matthew Wilcox: add historical context for argument]
