drm_vma_node_revoke(9)

✨ drm_vma_node_revoke — it's giving "you're uninvited from the party" 💅

okay so real quick, bestie: this is a page from the Kernel API Manual, and it's all about drm_vma_node_revoke(9) — the function that takes somebody's name off the guest list 🎀

---

🌸 NAME 🌸

drm_vma_node_revoke — remove open-file from list of allowed users

like… think of it as the bouncer politely walking one specific file out of the VIP area 🚪✨

---

🦋 SYNOPSIS 🦋

void drm_vma_node_revoke (struct drm_vma_offset_node *node , struct
drm_file *tag );

no cap, that's the whole signature 💖

---

🎀 ARGUMENTS 🎀

• node — node to modify. this is the thing you're editing, the main character of the operation 👑
• tag — tag of file to remove. the one getting de-listed, sorry bestie 🙈

---

💜 DESCRIPTION 💜

so here's the tea ☕ — this decrements the ref-count of tag in the list of allowed open-files on node. if the ref-count drops to zero, tag gets removed from the list. literally "count hits zero → you're out" ✨

⚠️ and this is the important bit, so listen up: you must call this once for every drm_vma_node_allow on tag. one revoke per allow, fr fr. don't be out here matching them up wrong 😭

this is locked against concurrent access internally — so the locking is already handled for you, no need to come up with your own, we love a self-sufficient function 🫶

and if tag is not on the list? nothing is done. it just… doesn't happen. no error, no drama, no nothing 💀 the function simply vibes past it.

and that's the page!! mwah 💋 this one came straight out of ./drivers/gpu/drm, dated October 2026, and yes it's the Kernel API Manual because we stay on the kernel side of things ⭐ periodt. now go balance your allow/revoke calls like the icon you are 👑🌸
