In multiple cases zio_buf_alloc() was used instead of kmem_alloc() or vmem_alloc(). This was often done because the allocations could be large and it was easy to use zfs_buf_alloc() for them. But this isn't ideal for allocations which are small or short lived. In these cases it is better to use kmem_alloc() or vmem_alloc(). If possible we want to avoid the case where we have slabs allocated for kmem caches which are rarely used. Note for small allocations vmem_alloc() will be internally converted to kmem_alloc(). Therefore as long as large allocations are infrequent and short lived the penalty for using vmem_alloc() is small.
