Stable bugfixes:
- Fall back to MDS if no deviceid is found rather than aborting # v4.11+
- NFS4: Fix v4.0 client state corruption when mount
Features:
- Much improved handling of soft mounts with NFS v4.0
- Reduce risk of false positive timeouts
- Faster failover of reads and writes after a timeout
- Added a "softerr" mount option to return ETIMEDOUT instead of
EIO to the application after a timeout
- Increase number of xprtrdma backchannel requests
- Add additional xprtrdma tracepoints
- Improved send completion batching for xprtrdma
Other bugfixes and cleanups:
- Return -EINVAL when NFS v4.2 is passed an invalid dedup mode
- Reduce usage of GFP_ATOMIC pages in SUNRPC
- Various minor NFS over RDMA cleanups and bugfixes
- Use the correct container namespace for upcalls
- Don't share superblocks between user namespaces
- Various other container fixes
- Make nfs_match_client() killable to prevent soft lockups
- Don't mark all open state for recovery when handling recallable state revoked flag

README
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.
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.
