okay so bestie, welcome to the dma_fence_unwrap_merge(9) page β¨ this one lives in the Kernel API Manual and it's literally about taking a whole pile of fences, unwrapping them, and merging them back into one flat vibe. no cap, it's giving "cleanup era" π§Ήπ
πΈ NAME πΈ
dma_fence_unwrap_merge β unwrap and merge fences π¦

dma_fence_unwrap_merge (... );
π ARGUMENTS π
...β variable arguments π« like, as many as you need, it's variadic and it's thriving.
π DESCRIPTION π
So here's the tea β: all the fences you hand over as parameters get unwrapped and then merged back together as a flat dma_fence_array. Slay. π
It's lowkey perfect if you've got multiple containers that need to be merged together β that's literally the whole point, iykyk π«Ά
It's implemented as a macro so it can allocate the necessary arrays on the stack and account the stack frame size to the caller. yes bestie, stack frame size accounting, we love a responsible icon πβ¨
On memory allocation failure it returns NULL π β otherwise you get a dma_fence object representing all the given fences. main character return value fr fr π
