Yangyang Li 9293d3fcb7 RDMA/hns: Use mutex instead of spinlock for ida allocation ... GFP_KERNEL may cause ida_alloc_range() to sleep, but the spinlock covering this function is not allowed to sleep, so the spinlock needs to be changed to mutex. As there is a certain chance of memory allocation failure, GFP_ATOMIC is not suitable for QP allocation scenarios.
