Subject: mon/OSDMonitor: invalidate max_failed_since on cancel_report
X-Git-Tag: v14.0.1~358^2
X-Git-Url: http://git-server-git.apps.pok.os.sepia.ceph.com/?a=commitdiff_plain;h=refs%2Fpull%2F23949%2Fhead;p=ceph.git

mon/OSDMonitor: invalidate max_failed_since on cancel_report

max_failed_since might reference the very failure-report which is to be
cancelled. We can simply invalidate it here to make **get_failed_since()**
recalculate if necessary.
