Kent Overstreet 0ba95acc44 bcachefs: Allow existing stripes to be updated with new data buckets
This solves internal fragmentation within stripes. We already have
copygc, which evacuates buckets that are partially or mostly empty, but
it's up to the ec code that manages stripes to deal with stripes that
have empty buckets in them.

This patch changes the path for creating new stripes to check if there's
existing stripes with empty buckets - and if so, update them with new
data buckets instead of creating new stripes.

TODO: improve the disk space accounting so that we can only use this
(more expensive path) when we have too much fragmentation in existing
stripes.

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.
