gsi_trans_pool_exit_dma(9)

💅 gsi_trans_pool_exit_dma — the Kernel API Manual, bestie edition 🎀

okay so this is a page from the Kernel API Manual, and the function it's hyping up is gsi_trans_pool_exit_dma(9). literally one job, and it's the glow-down: it's the inverse of gsi_trans_pool_init_dma(). that's the whole vibe. you set a DMA pool up with the init one, and this one undoes it. periodt. ✨

✨ SYNOPSIS ✨

void gsi_trans_pool_exit_dma (struct device *dev , struct gsi_trans_pool
*pool );

no cap, that's it — returns void, takes two args, doesn't even give you a return value to obsess over. iconic, lowkey 🦋

🫶 ARGUMENTS 🫶

• dev — the device used for DMA. like, the actual device. this is the main character of the DMA situation ngl 💖
• pool — the pool pointer. it's a pointer. to the pool. you're pointing at the pool. that's the whole thing 🌸
