osdc: pass fadvise op flags to WritebackHandler read requests
librbd was previously attempting to cast the provided Context to
retrieve the fadvise flags. To eliminate the unsafe cast, now
the fadvise flags are directly passed to the WritebackHandler::read
callback.

osd/OSDMap: include pg_temp count in summary
It is useful to know how big the pg_temp map is. Strictly speaking
this is part of the OSDMap so I'm including it here. It looks like
this:
osdmap e25: 3 osds: 3 up, 3 in; 1 remapped pgs
It might be more user-friendly to put it in a line with the pgmap
somewhere (where other pg counts are included), but it doesn't quite
fit there either. So sticking with where it lives in the data
structure!
It was possible for ImageWatcher to attempt to re-acquire held locks
via context callbacks. This issue affected resizing/flattening when
no work was required and rescheduling a watch upon two successive
failures.

librbd: enforce write ordering with snapshot
The md_lock is now held for reading when scheduling write/discards.
Since snap_create now holds the lock for writing and flushes all
pending IO, write/discard operations will now be consistent for a

librbd: use separate files for snapshot object maps
Instead of relying on the built-in object snapshot support,
create a separate object map object for each image snapshot.

tests: remove tests for when init() is not called in shec (#10839)
init2_1, init2_2, init2_3 are equivalent to init_1 and also removed.
encode_6, decode_6, create_ruleset_3 are null argument tests,

mon: MonCap: take EntityName instead when expanding profiles
entity_name_t is tightly coupled to the messenger, while EntityName is
tied to auth. When expanding profiles we want to tie the profile
expansion to the entity that was authenticated. Otherwise we may incur
in weird behavior such as having caps validation failing because a given
client messenger inst does not match the auth entity it used.

entity_name_t during profile expansion would not allow the client access

Otherwise, we can't return the correct user version on a dup request.
Note: This patch does not handle compatilibity with the variant which

and we haven't had a release, I think that's ok since handling
compatilibity would require some overhead in the encode/decode
