vchan_issue_pending(9)

💅 NAME 💅

okay so this is the vchan_issue_pending(9) page from the Kernel API Manual, and its whole job is literally: move submitted descriptors to the issued list. that's it, that's the vibe. ✨

---

🦋 SYNOPSIS 🦋

bool vchan_issue_pending (struct virt_dma_chan *vc );

---

🎀 ARGUMENTS 🎀

• vc — the virtual channel you're updating, bestie. that's the one getting the glow-up. 💖

---

🌸 DESCRIPTION 🌸

so here's the tea: vc.lock must be held by the caller. no cap, that's a requirement, not a suggestion. 🔒

⚠️ like actually hold vc.lock before you call this — the page says it must be held by caller, and we do not play about locking. 💀
