Christoph Hellwig 4f0cd5a555 xfs: split out a btree type from the btree ops geometry flags
Two of the btree cursor flags are always used together and encode
the fundamental btree type.  There currently are two such types:

 1) an on-disk AG-rooted btree with 32-bit pointers
 2) an on-disk inode-rooted btree with 64-bit pointers

and we're about to add:

 3) an in-memory btree with 64-bit pointers

Introduce a new enum and a new type field in struct xfs_btree_geom
to encode this type directly instead of using flags and change most
code to switch on this enum.

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.
