Re: [PATCH v2 0/7] http: minor improvements

> Changes from v1 (based on comments from Clemens):
>   - patch 3: don't say "remove condition", since we're actually enabling
>     it.
>   - patch 5: in keeping with separating http and http-walker, removed
>     http_cleanup() from http-walker->cleanup().
>   - patch 5: move http_cleanup() call after http-walker->cleanup(). This
>     isn't really needed, but do this just in case http-walker->cleanup()
>     does any http operations.
