Merge tag 'nfs-for-4.19-1' of git://git.linux-nfs.org/projects/anna/linux-nfs
Pull NFS client updates from Anna Schumaker:
"These patches include adding async support for the v4.2 COPY
operation. I think Bruce is planning to send the server patches for
the next release, but I figured we could get the client side out of
the way now since it's been in my tree for a while. This shouldn't
cause any problems, since the server will still respond with
synchronous copies even if the client requests async.
Features:
- Add support for asynchronous server-side COPY operations
Stable bufixes:
- Fix an off-by-one in bl_map_stripe() (v3.17+)
- NFSv4 client live hangs after live data migration recovery (v4.9+)
- xprtrdma: Fix disconnect regression (v4.18+)
- Fix locking in pnfs_generic_recover_commit_reqs (v4.14+)
- Fix a sleep in atomic context in nfs4_callback_sequence() (v4.9+)

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
