free_dma_desc_resources(9)

💅 free_dma_desc_resources(9) — a Kernel API Manual moment 💅

okay so bestie, welcome to the Kernel API Manual, entry free_dma_desc_resources(9). this one is short, sweet, and honestly a little iconic — it's the cleanup girlie of the stmmac DMA desc resources world 🌸

---

✨ NAME ✨

free_dma_desc_resources — free dma desc resources 🧹💖

like, literally the function that frees the dma desc resources. that's the whole vibe. no cap.

---

🌈 SYNOPSIS 🌈

void free_dma_desc_resources (struct stmmac_priv *priv , struct
       stmmac_dma_conf *dma_conf );

returns void, so don't go looking for a return value bestie, there isn't one 🫶

---

🎀 ARGUMENTS 🎀

• priv — private structure 🦋 (yes that's really all it says, it's giving "you already know")
• dma_conf — structure to take the dma data 💫

so yeah, that's the page. short king energy, but every single reference is accounted for 💅✨

and for the cute sign-off: this little number comes to you from the source/version line ./drivers/net/ethernet/stmicro..., dated October 2026 🎀🦋 and the manual name? it's free_dma_desc_resources(9), obviously — mwah 💖
