[PATCH net 0/3] mptcp: rx path fixes

[Matthieu Baerts (NGI0)]

Here are 3 different fixes, all related to the MPTCP receive buffer:

- Patch 1: fix receive buffer space when recvmsg() blocks after
  receiving some data. For a fix introduced in v6.12, backported to
  v6.1.

- Patch 2: mptcp_cleanup_rbuf() can be called when no data has been
  copied. For 5.11.

- Patch 3: prevent excessive coalescing on receive, which can affect the
  throughput badly. It looks better to wait a bit before backporting
  this one to stable versions, to get more results. For 5.10.

Please note that there is no urgency here as well: this can of course be
sent to Linus next year!

Enjoy this holiday period!
