From the diff of that commit:

-What: Multipath cached routing support in ipv4
-When: in 2.6.23
-Why: Code was merged, then submitter immediately disappeared leaving
- us with no maintainer and lots of bugs. The code should not have
- been merged in the first place, and many aspects of it's
- implementation are blocking more critical core networking
- development. It's marked EXPERIMENTAL and no distribution
- enables it because it cause obscure crashes due to unfixable bugs
- (interfaces don't return errors so memory allocation can't be
- handled, calling contexts of these interfaces make handling
- errors impossible too because they get called after we've
- totally commited to creating a route object, for example).
- This problem has existed for years and no forward progress
- has ever been made, and nobody steps up to try and salvage
- this code, so we're going to finally just get rid of it.
