Subject: [PATCH net-next 00/10] rxrpc: Miscellaneous fixes


Here's a set of miscellaneous fix patches.  There are a couple of points of
note:

 (1) There is one non-fix patch that adjusts the call ref tracking
     tracepoint to make kernel API-held refs on calls more obvious.  This
     is a prerequisite for the patch that fixes prealloc refcounting.

 (2) The final patch alters how jumbo packets that partially exceed the
     receive window are handled.  Previously, space was being left in the
     Rx buffer for them, but this significantly hurts performance as the Rx
     window can't be increased to match the OpenAFS Tx window size.

     Instead, the excess subpackets are discarded and an EXCEEDS_WINDOW ACK
     is generated for the first.  To avoid the problem of someone trying to
     run the kernel out of space by feeding the kernel a series of
     overlapping maximal jumbo packets, we stop allowing jumbo packets on a
     call if we encounter more than three jumbo packets with duplicate or
     excessive subpackets.

The patches can be found here also (non-terminally on the branch):
