I have confirmed that the kernel version used in our test already contains this patch, but the phenomenon
still exists on our platform. The previous log is recorded under the condition that the interval of the
perftest test is long, and the system will hang. Calltrace will be available when the test interval is short.
the kernel version as following:
commit dc75d8f9bf27647013bbfae1e2f1d114546994c4

{fromtree} RDMA: Move owner into struct ib_device_ops
This more closely follows how other subsytems work, with owner being a
member of the structure containing the function pointers.
