- OSD/MDS latency and caps cache metrics infrastructure for the
filesytem (Xiubo Li). Currently available through debugfs and
will be periodically sent to the MDS in the future.
- support for replica reads (balanced and localized reads) for
rbd and the filesystem (myself). The default remains to always
read from primary, users can opt-in with the new crush_location
and read_from_replica options. Note that reading from replica
is safe for general use only since Octopus.
- support for RADOS allocation hint flags (myself). Currently
used by rbd to propagate the compressible/incompressible hint
given with the new compression_hint map option and ready for
passing on more advanced hints, e.g. based on fadvise() from
the filesystem.
- support for efficient cross-quota-realm renames (Luis Henriques)
- assorted cap handling improvements and cleanups, particularly
untangling some of the locking (Jeff Layton)

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.
