Maor Gottlieb 22c3653d04 IB/mlx4: Take write semaphore when changing the vma struct ... When the driver disassociate user context, it changes the vma to anonymous by setting the vm_ops to null and zap the vma ptes. In order to avoid race in the kernel, we need to take write lock before we change the vma entries.
