[PATCH blktests v3 0/6] Add SRP initiator driver tests

[Bart Van Assche <bart.vanassche@wdc.com>]

Hello Omar,

As promised during LSF/MM, I have converted the srp-tests software to the
blktests framework. Please consider this patch series for inclusion in the
official blktests repository. This patch series is also available as a
github pull request, namely https://github.com/osandov/blktests/pull/24.

Thanks,

Bart.

Changes compared to v2:
- Instead of documenting which kernel configuration options are required in
  README.md, skip the SRP tests if not all required kernel configuration
  options have been set.
- Renamed tests/srp/functions into tests/srp/rc.
- Made sure that the SRP test cleanup code is run if a test is interrupted
  with Ctrl-C.
- Fixed the syntax of the fio command line: changed -rw=... into --rw=...
- Suppressed the "Unloaded the ... kernel module" messages.
- Moved the multipath configuration data from README.md into
  tests/srp/multipath.conf. With this change /etc/multipath.conf can be a
  soft link and copy/pasting multipath configuration data is no longer required.
- multipathd is now started and stopped during each test instead of requiring
  that it is started before running any tests.
- Added "find_multipaths no" to multipath.conf for Arch Linux.
- The null_blk driver is now used instead of brd.
- If a PCI RDMA adapter is present in the test system, the SRP initiator not
  only connects over the rdma_rxe driver but also uses the loopback
  functionality of the PCI RDMA adapter.
- A list of which SRP connections have been created is written into the $FULL
  file.
- It is no longer attempted to associate the rdma_rxe driver with IPoIB network
  interfaces.

Changes compared to v1:
- Left out the patches from version one of this series that are already
  upstream.
- Renamed tests/srp/group into tests/srp/rc.
- The SRP tests do not start if LIO was already configured (reported by Ming).
- Documented the SRP test requirements in README.md.
