The incoming qgroup reserved space timing will move the data reservation to ordered extent completely. However in btrfs_punch_hole_lock_range() will call btrfs_invalidate_page(), which will clear QGROUP_RESERVED bit for the range. In current stage it's OK, but if we're making ordered extents handle the reserved space, then btrfs_punch_hole_lock_range() can clear the QGROUP_RESERVED bit before we submit ordered extent, leading to qgroup reserved space leakage. So here change the timing to make reserve data space after btrfs_punch_hole_lock_range(). The new timing is fine for either current code or the new code.

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.
