This introduces a new version of KEY_TYPE_alloc, which uses the new varint encoding introduced for inodes. This means we'll eventually be able to support much larger bucket sizes (for SMR devices), and the read/write time fields are expanded to 64 bits - which will be used in the next patch to get rid of the periodic rescaling of those fields. Also, for buckets that are members of erasure coded stripes, this adds persistent fields for the index of the stripe they're members of and the stripe redundancy. This is part of work to get rid of having to scan and read into memory the alloc and stripes btrees at mount time.

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.
