tcp_splice: Use unsigned to represent side
Currently, we use 'int' values to represent the "side" of a connection, which must always be 0 or 1. This turns out to be dangerous. In some cases we're going to want to put the side into a 1-bit bitfield. However, if that bitfield has type 'int', when we copy it out to a regular 'int' variable, it will be sign-extended and so have values 0 and -1, instead of 0 and 1. To avoid this, always use unsigned variables for the side. Signed-off-by: David Gibson <david@gibson.dropbear.id.au> Signed-off-by: Stefano Brivio <sbrivio@redhat.com>
