btree_gc sometimes needs another pass when it corrects bucket generation numbers or data types - when it finds multiple pointers of different data types to the same bucket, it may want to keep the second one it found. When this happens, we now clear out bucket sector counts _without_ resetting the bucket generation/data types that we already found, instead of resetting them to what we have in the alloc btree.

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.
