Gu Jinxiang 019599ada7 btrfs: use reada direction enum instead of constant value in populate_free_space_tree
populate_free_space_tree calls function btrfs_search_slot_for_read with
parameter int find_higher = 1, it means that, if no exact match is
found, then use the next higher item.  So in function
populate_free_space_tree, use READA_FORWARD to read forward ahead.

This also changes the value from READA_BACK to READA_FORWARD, since
according to the logic, it should reada_for_search forward, not
backward.

README

Linux kernel
============

This file was moved to Documentation/admin-guide/README.rst

Please notice that there are several guides for kernel developers and users.
These guides can be rendered in a number of formats, like HTML and PDF.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
