Re: [PATCH] dma-buf: add get_dma_buf()

reference count at dma_buf_fd I prefer solution (b) because it prevents symmetry between dma_buf_fd and close. I mean that dma_buf_fd increases reference count, close decreases it. What is your opinion about the issue? Regards, Tomasz Stanislawski On 03/16/2012 05:04 PM, Rob Clark wrote: &
