That does make it a bit clearer, but I do hope the compiler optimizes away the redundant curr variable.
Now, on a different note, I am a bit puzzled because I don’t see a free(*ptr) call in Linus’ or anyone else’s code. The code, as-is, would cause a memory leak.
There’s a need to capture the curr_ref before it’s overwritten, and free it after it’s overwritten.
