Since the CoW fork only exists in memory, it is incorrect to update the on-disk quota block counts when we modify the CoW fork. Unlike the data fork, even real extents in the CoW fork are only delalloc-style reservations (on-disk they're owned by the refcountbt) so they must not be tracked in the on disk quota info. Ensure the i_delayed_blks accounting reflects this too. Signed-off-by: Darrick J. Wong <darrick.wong@oracle.com> Reviewed-by: Christoph Hellwig <hch@lst.de>
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.
