    Description

      Console log messages following this pattern, repeatedly, for several days:

      LustreError: 67801:0:(import.c:361:ptlrpc_invalidate_import()) lsrza-OST0000_UUID: rc = -110 waiting for callback (1 != 0)

      Note that the number in the parentheses is 0. This refers to imp->imp_unregistering, an atomic variable that looks like it is intended to track the number of RPC buffers we ware waiting for the underlying network to unregister so know that no data will be lost. But there is still one RPC on the sending list, so why is imp_unregistering 0?
