xilinx_dma_c...desc_cleanup(9)

✨ xilinx_dma_chan_desc_cleanup ✨

okay bestie, welcome to the Kernel API Manual section 9 entry for xilinx_dma_c...desc_cleanup — yes the title is truncated in the header like that, that's just how the man page shows up, and no I can't fix it, it's giving "name too long for the label maker" 💅

---

🌸 NAME 🌸

xilinx_dma_chan_desc_cleanup — clean the channel descriptors, that's literally the whole job 🧹✨

---

🦋 SYNOPSIS 🦋

void xilinx_dma_chan_desc_cleanup(struct xilinx_dma_chan *chan);

like, that's it, that's the whole call. one argument, void return, no cap. 🫶

---

🎀 ARGUMENTS 🎀

• chan — the driver-specific DMA channel 💖 this is the channel you're cleaning descriptors for, so bestie, hand over a real one.

bestie reminder: this page is short on purpose, so don't go inventing extra behaviour for it. everything it does is "clean channel descriptors" and everything else is in those SEE ALSO pages, iykyk 🌈

and that's the page!! mwah 🎀 this little beauty lives in ./drivers/dma/xilinx and the version/date stamp on it is October 2026 — iconic, timeless, slay, periodt 🌟👑
