No, at this point kernel receives only one buffer and fills it up. Can you pls elaborate more what improvement you have in mind? Like user-space sending a list of buffers to the kernel in one shot? Or that user-space handles kind of producer-consumer pool of buffers and works on full buffers while kernel fills the empty ones (this, of course, can work). In general, my direction was to make the kernel call stateless, which makes the user-space part more flexible.
