OSD recomputes op target based on current OSDMap. With an EC pg, we can get
this result:
1) client at map 512 sends an op to osd 3, pg_t 3.9 based on mapping
[CRUSH_ITEM_NONE, 2, 3]/3
2) OSD 3 at map 513 remaps op to osd 3, spg_t 3.9s0 based on mapping [3, 2, 3]/3
3) PG 3.9s0 dequeues the op at epoch 512 and notices that it isn't
primary -- misdirected op
4) client resends and this time PG 3.9s0 having caught up to 513 gets it and
fulfils it
We can't compute the op target based on the sending map epoch due to
splitting. The simplest thing is to detect such cases in
OSD::handle_misdirected_op and drop them without an error (the client
will resend anyway).

be2748c6d5 ensured that
if the temp acting mapping contains only CRUSH_ITEM_NONE,
that the acting_primary is left at -1. However, even if
acting.empty(), we need to respect a temp_primary mapping.
Thus, use _acting_primary unless acting.empty() &&
acting_primary == -1.
Bug introduced in be2748c6d5.

Since backfill peers are no longer placed into the acting set,
temp mappings will never exceed the pool size. Also, for ec
pools, temp mappings will never be less than the pool size.

If we are encoding a full map based on an old Incremental that does not
encode the features, fall back to the quorum features or (barring that)
all features. Do *not* do no features or else we will end up with
encode_client_old which does not even include the extended info and will
cause the mon to crash when decoding.
This was observed when upgading a 0.76 cluster to 0.77 (all mons stopped,
upgraded, and then started)

The insert() call here does not overwrite a previous entry, which means
that the osd_epochs map is never moving forward in time. This seems to
have been broken since it was introduced in 091809b814.

There are two paths that jump to the out label for which 'in' can be
NULL and outp can be non-NULL. For those cases we want to fill in the
caller's pointer value (they asked for it) but we clearly cannot take
a reference.
