      "message": "ceph: properly handle aborted mds requests\n\nPreviously, if the MDS request was interrupted, we would unregister the\nrequest and ignore any reply.  This could cause the caps or other cache\nstate to become out of sync.  (For instance, aborting dbench and doing\nrm -r on clients would complain about a non-empty directory because the\nclient didn\u0027t realize it\u0027s aborted file create request completed.)\n\nEven we don\u0027t unregister, we still can\u0027t process the reply normally because\nwe are no longer holding the caller\u0027s locks (like the dir i_mutex).\n\nSo, mark aborted operations with r_aborted, and in the reply handler, be\nsure to process all the caps.  Do not process the namespace changes,\nthough, since we no longer will hold the dir i_mutex.  The dentry lease\nstate can also be ignored as it\u0027s more forgiving.\n\nSigned-off-by: Sage Weil \u003csage@newdream.net\u003e\n"
