Bart Van Assche 509c5f33f4 IB/srp: Prevent mapping failures ... If both max_sectors and the queue_depth are high enough it can happen that the MR pool is depleted temporarily. This causes the SRP initiator to report mapping failures. Although the SRP initiator recovers from such mapping failures, prevent that this can happen by allocating more memory regions. Additionally, only enable memory registration if at least two pages can be registered per memory region.
