Commit 01e7da6ba53ca4d6189a1eae45607c0331c871f2 introduced a potential
problem wherein the cq's comp_handler can get called simultaneously from
different places in iw_cxgb4 driver. This does not comply with
Documentation/infiniband/core_locking.txt, which states that at a given
point of time, there should be only one callback per CQ should be active.
This problem was reported by Parav Pandit<parav.pan...@emulex.com>.
Based on discussion between Parav Pandit and Steve Wise, this patch
aims to correct above problem by serializing the calls to cq's comp_handler
using a spin_lock.
