David Sterba 01cd390903 Revert "btrfs: turn fs_info member buffer_radix into XArray" This reverts commit `8ee922689d`. Revert the xarray conversion, there's a problem with potential sleep-inside-spinlock [1] when calling xa_insert that triggers GFP_NOFS allocation. The radix tree used the preloading mechanism to avoid sleeping but this is not available in xarray. Conversion from spin lock to mutex is possible but at time of rc6 is riskier than a clean revert.

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.
