Qu Wenruo 0a55f346e0 btrfs: qgroup: catch reserved space leaks at unmount time
[ Upstream commit 5958253cf65de42493f17f36877a901486a90365 ]

Before this patch, qgroup completely relies on per-inode extent io tree
to detect reserved data space leak.

However previous bug has already shown how release page before
btrfs_finish_ordered_io() could lead to leak, and since it's
QGROUP_RESERVED bit cleared without triggering qgroup rsv, it can't be
detected by per-inode extent io tree.

So this patch adds another (and hopefully the final) safety net to catch
qgroup data reserved space leak.  At least the new safety net catches
all the leaks during development, so it should be pretty useful in the
real world.

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.
