In xfs_iomap_write_unwritten, we need to ensure that dquots are attached to the inode and quota blocks reserved so that we capture in the quota counters any blocks allocated to handle a bmbt split. This can happen on the first unwritten extent conversion to a preallocated sparse file on a fresh mount. This was found by running generic/311 with quotas enabled. The bug seems to have been introduced in "[XFS] rework iocore infrastructure, remove some code and make it more" from ~2002? Signed-off-by: Darrick J.

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.
