✨ ttm_resource_manager_set_used ✨

okay so bestie, this is a Kernel API Manual page for ttm_resource_manager_set_used(9) — the little function that flips the "we're using this memory manager" switch. no cap, it's short but it's lowkey important 💅

---

🌸 SYNOPSIS 🌸

void ttm_resource_manager_set_used (struct ttm_resource_manager *man ,
bool used );

it's giving "two arguments, one job" energy, and honestly? we stan a focused function 🫶

---

🦋 ARGUMENTS 🦋

• man — A memory manager object. that's the main character right there, the struct getting its flag adjusted 👑
• used — usage state to set. basically "are we using this or not" as a bool, and you're deciding 😌

---

💖 DESCRIPTION 💖

so here's the tea ☕: this function sets the manager in use flag. that's it, that's the whole vibe.

but like, here's the important part — if it's disabled, the manager is no longer used for object placement. so like, it stops being picked for where objects go. not me casually removing a manager from the object-placement rotation 😭 it's not deprecated or anything, it's just a straight-up state toggle, so set used to whatever you actually mean, bestie. no guessing, no cap.
