Hi, These are a set of patches which removes semaphores from infiniband. These are part of a bigger effort to eliminate all semaphores from the linux kernel.
NB: A few semaphores which are counting ones are replaced with an open-coded implementation by introducing a new type in 'include/rdma/ib_sa.h'. Need to see if this can be programmed in a generic way using wait queues.
