Does anyone know whether it's safe to revert commit 4cdd2ad780 ? Anyway, I ran a test with v3.15-rc7 + your patch + 4cdd2ad780 reverted and that test ran fine. I didn't encounter any lockups nor any lockdep complaints. The test I ran was to run a fio I/O verification test on top of a dm-multipath device. That multipath device was created on top of several SCSI device nodes created by the ib_srp driver. About once every 30 seconds a cable removal / reinsertion was simulated via the ibportstate command.
