Merge branch 'mptcp-avoid-workqueue-usage-for-data'
Paolo Abeni says:
====================
mptcp: avoid workqueue usage for data
The current locking schema used to protect the MPTCP data-path
requires the usage of the MPTCP workqueue to process the incoming
data, depending on trylock result.
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.
