    IB/mthca: Get rid of might_sleep() annotations · 399d7921
    Roland Dreier authored
    The might_sleep() annotations in mthca are silly -- they all occur
    shortly before calls that will end up in core functions like kmalloc()
    that will print the same warning in an unsafe context anyway.  In
    fact, beyond cluttering the source, we're actually bloating text with
    CONFIG_DEBUG_SPINLOCK_SLEEP and/or CONFIG_PREEMPT_VOLUNTARY set.
    
    With both options set, getting rid of the might_sleep()s saves a lot:
