The above poses scalability limits and introduces random delays in MPTCP-level acks. With this series we use a single spinlock to protect the MPTCP data-path, removing the need for workqueue and delayed ack usage. This additionally reduces the number of atomic operations required per packet and cleans-up considerably the poll/wake-up code. ==================== Link: https://lore.kernel.org/r/cover.1606413118.git.pabeni@redhat.com Signed-off-by: Jakub Kicinski --- 5f3e915c36d59c94a917e207df4361f23d9c821d
