7061a6ee8d ib_srpt: Make the completion vector configurable 
Allow a set of completion vectors to be associated with each InfiniBand
HCA port and allocate the completion vector for each session in a
round-robin fashion from the per-port set. This helps to spread the
InfiniBand interrupt workload over multiple CPU's, at least if different
InfiniBand MSI-X vectors are associated with different CPU's.

When unloading the ib_srpt kernel module, instead of waiting until
all connected queue pairs have left the TimeWait state, destroy
these queue pairs immediately.

97167af582 scst: Make lockdep_assert_held() easier to use 
The lockdep_assert_held() macro is a convenient debugging tool.
However, it is inconvenient to surround each invocation of that
macro by an #ifdef/#endif pair. Hence make it easier to use this
macro with older kernel versions.
