Andrzej Hajda d396f97648 debugobjects: Stop accessing objects after releasing hash bucket lock ... [ Upstream commit 9bb6362652 ] After release of the hashbucket lock the tracking object can be modified or freed by a concurrent thread. Using it in such a case is error prone, even for printing the object state: 1. T1 tries to deactivate destroyed object, debugobjects detects it, hash bucket lock is released. 2. T2 preempts T1 and frees the tracking object. 3. The freed tracking object is allocated and initialized for a different to be tracked kernel object. 4. T1 resumes and reports error for wrong kernel object. Create a local copy of the tracking object before releasing the hash bucket lock and use the local copy for reporting and fixups to prevent this.
