[PATCH] radix-tree: Remove unnecessary indirections and clean up code
- There is frequent use of indirections in the radix code. This patch
removes those indirections, makes the code more readable and allows
the compilers to generate better code.
- Removing indirections allows the removal of several casts.
- Removing indirections allows the reduction of the radix_tree_path
size from 3 to 2 words.
- Use pathp-> consistently.
- Remove unnecessary tmp variable in radix_tree_insert
- Separate the upper layer processing from the lowest layer in __lookup()
in order to make it easier to understand what is going on and allow
compilers to generate better code for the loop.
