Ilya Dryomov 29a0cfbf91 libceph: don't allow bidirectional swap of pg-upmap-items ... This reverts most of commit f53b7665c8 ("libceph: upmap semantic changes"). We need to prevent duplicates in the final result. For example, we can currently take [1,2,3] and apply [(1,2)] and get [2,2,3] or [1,2,3] and apply [(3,2)] and get [1,2,2] The rest of the system is not prepared to handle duplicates in the result set like this. The reverted piece was intended to allow [1,2,3] and [(1,2),(2,1)] to get [2,1,3] to reorder primaries. First, this bidirectional swap is hard to implement in a way that also prevents dups. For example, [1,2,3] and [(1,4),(2,3),(3,4)] would give [4,3,4] but would we just drop the last step we'd have [4,3,3] which is also invalid, etc. Simpler to just not handle bidirectional swaps. In practice, they are not needed: if you just want to choose a different primary then use primary_affinity, or pg_upmap (not pg_upmap_items).
