Subject[PATCH] lib/radix-tree: Remove unused argument of insert_entries
Date
Function 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]
