Hi Linus,

I'm filling in for Bruce this time while he and his family settle
into a new house.


The following changes since commit fb33c6510d5595144d585aa194d377cf74d31911:

  svcrdma: Fix leak of transport addresses (2020-03-27 12:25:06 -0400)

----------------------------------------------------------------
Highlights:

- Fix EXCHANGE_ID response when NFSD runs in a container
- A battery of new static trace points
- Socket transports now use bio_vec to send Replies
- NFS/RDMA now supports filesystems with no .splice_read method
- Favor memcpy() over DMA mapping for small RPC/RDMA Replies
- Add pre-requisites for supporting multiple Write chunks
- Numerous minor fixes and clean-ups

There are a few open issues that did not reach closure before I cut
the nfsd-5.7 tag:

- Vasily Averin has addressed a use-after-free in nfsd4_lock()
- Yihao Wu is investigating a race in cache_purge()
- Jan Psota reports a refcount underflow warning in nfsd41_cb_destroy()

These are long-standing bugs. I plan to send follow-up PRs for
v5.7-rc when these issues are resolved and their fixes thoroughly
tested.
