Prepending data to struct uio in kernel

I wish to insert a small buffer into (actually in front of) a uio structure
received from userland through an ioctl call. I then want to map this uio
structure to a dma map.
Currently I am mallocing a new buffer, copying the uio data and my own data
to that buffer and then mapping the buffer to DMA.
Is it possible to insert data into a uio structure?
Are there any functions that might help me?
Is it a bad idea?
(I do hope this is not to the incorrect list)
