primarily used for testing, but which can be useful on production systems when a scratch volume is being destroyed and the data on it doesn't need to be saved. This found (and we fixed) a number of bugs with ext4's recovery to corrupted file system --- the bugs increased the amount of data that could be potentially lost, and in the case of the inline data feature, could cause the kernel to BUG. Also included are a number of other bug fixes, including in ext4's fscrypt, DAX, inline data support. -----BEGIN PGP SIGNATURE----- iQEzBAABCAAdFiEEK2m5VNv+CHkogTfJ8vlZVpUNgaMFAlirXesACgkQ8vlZVpUN gaMOzQf8Ct6uPatV+m855oR4dAbZr2+lY4A4C+vHDzBtSMkPRyLX8cuo8XcwfTIm vPVyDnL6EPyhXPxxfItu+92wAq1m5mVpKo57d0Ft5lw0rHxNtJTgVSRzsQ7VDRjj 5qMHW2K7Bk7EjzTeW3SF8/3+hqpzkAvRtNCntcomk5h08+cWMC8JSnn1kqw+naIn EcbrC72GZb8JUELogVXC2vU58lp50SSBdr3l005jqKc5BvljMvdJ0Izn/3RVyU7u q7vtynhe2ScFcHe/UzL1QgmQOy32tJpbS0NHalW47aw3Ynmn4cSX0YhhT9FDjRNQ VOOfo1m1sAg166x0E+Nn7FeghTSSyA== =cPIf -----END PGP SIGNATURE----- Merge tag 'ext4_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tytso/ext4 Pull ext4 updates from Ted Ts'o: "For this cycle we add support for the shutdown ioctl, which is primarily used for testing, but which can be useful on production systems when a scratch volume is being destroyed and the data on it doesn't need to be saved.

README
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.
