The purpose of this InfiniBand SRP initiator patch series is as follows:
- Make the SRP initiator driver better suited for use in a H.A. setup.
Add fast_io_fail_tmo, dev_loss_tmo and reconnect_delay parameters.
With the default values of these parameters failover happens
significantly
Keep the rport data structure around after srp_remove_host() has
finished until cleanup of the IB transport layer has finished
completely. This is necessary because later patches use the rport
pointer inside the queuecommand callback. Without this patch
accessing the rport from inside a
Add the necessary functions in the SRP transport module to allow
an SRP initiator driver to implement transport layer error handling
similar to the functionality already provided by the FC transport
layer. This includes:
- Support for implementing fast_io_fail_tmo, the time that should
elapse
Add support for periodically reconnecting to an SRP target until
the dev_loss timer expires. After the tenth reconnection attempt,
gradually slow down subsequent reconnect attempts.

pci_enable_msix() may fail, but it can not return a positive number.
That is true according to the current logic but the comment on top of
pci_enable_msix() still says:
A return of 0 indicates a failure. Or a return of 0
Fix crash after xri limit is reached.
