+
+    osd/ReplicatedPG: carry CopyOpRef in copy_from completion
+
+    There is a race with copy_from cancellation.  The internal Objecter
+    completion decodes a bunch of data and copies it into pointers provided
+    when the op is queued.  When we cancel, we need to ensure that we can cope
+    until control passes back to our provided completion.
+
+    Once we *do* get into the (ReplicatedPG) callbacks, we will bail out
+    because the tid in the CopyOp or FlushOp no longer matches.
+
+    Fix this by carrying a ref to keep the copy-from targets alive, and
+    clearing out the tids that we cancel.
+
+    Note that previously, the trigger for this was that the tid changes when
+    we handle a redirect, which made the op_cancel() call fail.  With the
+    coming Objecter changes, this will no longer be the case.  However, there
+    are also locking and threading changes that will make cancellation racy,
+    so we will not be able to rely on it always preventing the callback.
+    Either way, this will avoid the problem.
+
+    Fixes: #7588
