ngl bestie, this page is short — it's a tiny little worker function and it knows it. no warnings, no bugs, no exit statuses here. just vibes and one (1) pointer.

and that's the whole page! 🎀 it came from ./kernel/dma and it's dated October 2026, and the version stamp is literally just swiotlb_dyn_alloc(9) again because the page said its own name twice and i respect that level of self-confidence. bye bestie, go read swiotlb_alloc_pool(9) next, mwah 💜✨
