020ec68ddc ib_srpt: Change default behavior from using SRQ to not using SRQ 
Although the non-SRQ mode needs more resources that mode has the
advantage that the end-to-end flow control mechanism is used.

From the IB spec:

C9-150.2.1: For QPs that are not associated with an SRQ, each HCA
receive queue shall generate end-to-end flow control credits. If
a QP is associated with an SRQ, the HCA receive queue shall not
generate end-to-end flow control credits.

c32f79f6c1 Revert T10-PI support 
The T10-PI patch (r6162) increases the time needed to run mkfs.ext4
over iSCSI from less than a second to several minutes. This is a
regression so revert the T10-PI patch until there is sufficient time
to find the root cause of this regression and to fix this regression.

4ac6d7a26d [PATCH] scst: Drop detect() method 
There is no need for a detect() method - code that is present in such
a method can be moved to module_init(). Hence declare this method
obsolete. Leave the detect pointer member in the target template for
now for out-of-tree SCST drivers.
