xdma_link_sg_desc_blocks(9)

💖 NAME 💖

okay so bestie, meet xdma_link_sg_desc_blocks — she links the SG descriptor blocks together for a DMA transfer. that's it, that's the whole job, and she does it flawlessly 💅✨

(this whole page lives in the Kernel API Manual, section 9, just so you know what vibe we're in 🎀)
