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>
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.
