💅 dma_fence_put(9)

okay so real talk bestie, this is a page straight out of the Kernel API Manual, and it's literally one function doing one job. no cap. it's dma_fence_put, and it's the "let go of the fence" girlie of the DRM/KMS world.

that's twenty-six (26) entries bestie, I counted so you don't have to 💀 every one of them is real and every one of them is listed, no edits, no skips, we don't do that here 🫶

also note the pairing: dma_fence_get(9) is the one that bumps the refcount up, and dma_fence_put(9) is the one up there ☝️ that brings it back down. balance. harmony. main character energy ✨
