When the Objecter timer\r\nerases the tick_event from its events queue and calls tick() to dispatch\r\nit, if the Objecter::rwlock is held by shutdown(), it waits there to get\r\nthe rwlock. However, inside the shutdown function, it checks the\r\ntick_event and tries to cancel it. The cancel_event function returns\r\nfalse since tick_event is already removed from the events queue. Thus\r\ntick_event is not set to NULL, and leads to this assertion failure.\r\n\r\nFix issue #11183.\r\n\r\nSigned-off-by: Zhiqiang Wang <zhiqiang.wang@intel.com>"},"comment":{"url":"https://api.github.com/repos/ceph/ceph/issues/comments/85882374","html_url":"https://github.com/ceph/ceph/pull/4169#issuecomment-85882374","issue_url":"https://api.github.com/repos/ceph/ceph/issues/4169","id":85882374,"user":{"login":"tchaikov","id":59071,"avatar_url":"https://avatars.githubusercontent.com/u/59071?v=3","gravatar_id":"","url":"https://api.github.com/users/tchaikov","html_url":"https://github.com/tchaikov","followers_url":"https://api.github.com/users/tchaikov/followers","following_url":"https://api.github.com/users/tchaikov/following{/other_user}","gists_url":"https://api.github.com/users/tchaikov/gists{/gist_id}","starred_url":"https://api.github.com/users/tchaikov/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/tchaikov/subscriptions","organizations_url":"https://api.github.com/users/tchaikov/orgs","repos_url":"https://api.github.com/users/tchaikov/repos","events_url":"https://api.github.com/users/tchaikov/events{/privacy}","received_events_url":"https://api.github.com/users/tchaikov/received_events","type":"User","site_admin":false},"created_at":"2015-03-25T06:53:38Z","updated_at":"2015-03-25T06:53:38Z","body":"@wonzhq and could you please tag this commit with `Fixes: #11183` instead of `Fix issue #11183`, or if you are sure that the later can be understood by tracker?"}}
