    [NET]: Fix skb_truesize_check() assertion · 78608ba0
    Chuck Lever authored
    The intent of the assertion in skb_truesize_check() is to check
    for skb->truesize being decremented too much by other code,
    resulting in a wraparound below zero.
    
    The type of the right side of the comparison causes the compiler to
    promote the left side to an unsigned type, despite the presence of an
    explicit type cast.  This defeats the check for negativity.
    
    Ensure both sides of the comparison are a signed type to prevent the
    implicit type conversion.
