If we try to reflink into a file with post-eof preallocations at an offset well past the preallocations, we increase i_size as one would expect. However, those allocations do not have page cache backing them, so they won't get cleaned out on their own. This leads to asserts in the collapse/insert range code and xfs_destroy_inode when they encounter delalloc extents they weren't expecting to find. Since there are plenty of other places where we dump those post-eof blocks, do the same to the reflink destination file before we start remapping extents. This was found by adding clonerange support to fsstress and running it in write-only mode. 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.
