🦋 ARGUMENTS 🦋

• uq_mgr — the usermode queue manager for this process. yeah, this process. yours. hi. 👋
• evf_mgr — the eviction fence manager that's getting checked and rearmed. she's the one being fussed over. 💖

🌸 DESCRIPTION 🌸

okay so the whole point of this function: before any queue operations proceed, she makes sure a valid and not-yet-signaled eviction fence is attached to the usermode queue. that's the check. that's the gatekeeping. 🚧

and if it is signalled? then she rearms a new eviction fence. fresh fence, new era, main character energy. ⭐

like literally do not do queue operations until this has run. she's the vibe check at the door, and the door is the queue. 🔥
