commit c1e8220bd316d8ae8e524df39534b8a412a45d5e upstream. If a program attempts to punch a hole on an inline data file, we need to convert it to a normal file first. This was detected using ext4/032 using the adv configuration. Simple reproducer: mke2fs -Fq -t ext4 -O inline_data /dev/vdc mount /vdc echo "" > /vdc/testfile xfs_io -c 'truncate 33554432' /vdc/testfile xfs_io -c 'fpunch 0 1048576' /vdc/testfile umount /vdc e2fsck -fy /dev/vdc Cc: stable@vger.kernel.org Signed-off-by: Theodore Ts'o <tytso@mit.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
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.
