cf04c8541a Implement building qla2xxx out of the kernel tree. For that 
BUILD_2X_MODULE=y should be passed to make. New module named
qla2xxx_scst. Obviously, to have it working, the original qla2xxx should
be either blacklisted, or removed from the target system.

9ea2e26aaa ib_srpt: Avoid stopping polling too early for IB completions. 
This resulted in unnecessary complaints about IB completions not being
received in time when removing the ib_srpt kernel module during I/O. Note:
it is still possible that such complaints occur, but much less frequent.
