The\nold code was only calling kick_requests after processing all incremental\nmaps in a message, so it was very possible to not resend a request that\nneeded to be resent.  This would make the osd eventually time out (at least\nwith the current default of osd timeouts enabled).\n\nThe correct approach is to scan requests on every map incremental.  This\npatch refactors the kick code in a few ways:\n - all requests are either on req_lru (in flight), req_unsent (ready to\n   send), or req_notarget (currently map to no up osd)\n - mapping always done by map_request (previous map_osds)\n - if the mapping changes, we requeue.  requests are resent only after all\n   map incrementals are processed.\n - some osd reset code is moved out of kick_requests into a separate\n   function\n - the \"kick this osd\" functionality is moved to kick_osd_requests, as it\n   is unrelated to scanning for request-\u003epg-\u003eosd mapping changes\n\nSigned-off-by: Sage Weil \u003csage@newdream.net\u003e\n"
