okay so bestie, welcome to the vmw_cursor_...atomic_check(9) page from the Kernel API Manual — yes the title is literally abbreviated like that, it's giving "we ran out of room on the header" energy 🎀 but don't worry, the full name is right down there and it slays.

Returns 0 on success ✨ — zero means we're good, we're slaying, we're moving on.

lowkey important: this is described as a chance to fail. so if the new state doesn't fit the requirements, this is where it gets caught. no cap.
