This series is a preparation work for future in-kernel MPTCP sockets usage. Here, two interfaces are implemented: read_sock and splice_read. As a result of this series, splice() with MPTCP sockets -- which was already supported -- is now improved.
- Patches 1-2: .read_sock implementation - Patches 3-4: .splice_read implementation - Patches 5-6: validate splice() support with MPTCP sockets.
