Title: #133: sbus: use sss_ptr_hash for hash tables
All the patches look sane.
I, personally, would like to see some message in the commit log. If you don't think
it's needed, feel free to just ignore this comment.
Also, tt's really a nitpick, but I'd change "sbus" to "SBUS"
in the commit short-log for all patches, but this can be easily done before pushing.
I'll ack the patch as soon as I get CI results.
