Cleanup #1768
closedosd_client: gratuitous ceph_monc_request_next_osdmap calls
0%
Description
kick_requests() is called from within a loop that iterates through multiple OSD map updates ... which means that it may be called multiple times in a row.
If some queued request does not have an OSD in the current map, kick_requests() issues a monitor request for a new map before returning ... even if we already have (but simply have not yet processed) the update that cures the problem.
It would be more efficient to simply have kick_requests() return a value indicating whether or not a new map is needed. ceph_osdc_handle_map() would ignore this value for all but the final call to kick_requests() and only request an updated map if required OSDs were still not available.

OSD client has been rewritten in 4.7. We now rely on handle_timeout(), which requests a new map if there are homeless requests.
