In this cycle, we don't have a highlighted feature enhancement, but mostly have fixed issues mainly in two parts: 1) zoned block device, 2) compression support. For zoned block device, we've tried to improve the power-off recovery flow as much as possible. For compression, we found some corner cases caused by wrong compression policy and logics. Other than them, there were some reverts and stat corrections. Bug fix: - use finish zone command when closing a zone - check zone type before sending async reset zone command - fix to assign compress_level for lz4 correctly - fix error path of f2fs_submit_page_read() - don't {,de}compress non-full cluster - send small discard commands during checkpoint back - flush inode if atomic file is aborted - correct to account gc/cp stats And, there are minor bug fixes, avoiding false lockdep warning, and clean-ups. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEE00UqedjCtOrGVvQiQBSofoJIUNIFAmTyemoACgkQQBSofoJI UNLLKQ//bupYGPOqAgKbd/s7FhtULMiiRmFVy7W2eoMIc/oeeXOGrzDAF/1NifLC WLV4uBNVTS4PS8D1vRzxZNEZt9aqPS0vQ8hxW/3nTI9Z425NX3nz7gLSxxmwIkIe xj++V6tvKPcCH0BfKvfFCtcxj09PsflgdEuT8w/sIkH6p4o+VEMFs1Lc9PQsjUmh epznK7JGBwpAxmHqI74n1eAw2CI6W+oKx23YDTNMBD6hmXTU0fkTeBURrOlSsUHZ nhafPecsrCEI+OpAj03G/7e/zt+iTUKdmHx9O5ir/P00vF/c+SU2vSwB97FiHqBi B4UmocTM0MAsU80PQcmE6aU3zgQFI0Yun5yZ24VeWjKTu76ssZSmT2HA/4RL+LLf AeAW4FSyfh76pls8X5IWfilxGLWq6kTzSZA0MF7dH2q7qlj5apL5wKpm/XH6POqn qELY/Y9+P1QuCcNL8BiYrgA5xBqVJ7Uw/6/6U3Y77PElc+Pwl3vI8UZ7uCOBrsXL e0TLXy23AJA6AS2DyLLziy669nXAZRb95B8TWMfEeVZIMFvCeeqYc74N8jOFa0T8 q6uQFZs+0cETLZA8MSZdlNhzvhJmbW6wgSIz++CEdikWSLBZMKWxBVjCPkkCY9uc DMh8zruSVbYPZWBTcxkMFEBJKKrU43++e7pb8ZoqTj4Pq1317b0= =Qa8+ -----END PGP SIGNATURE----- Merge tag 'f2fs-for-6-6-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs Pull f2fs updates from Jaegeuk Kim: "In this cycle, we don't have a highlighted feature enhancement, but mostly have fixed issues mainly in two parts: 1) zoned block device, and 2) compression support.

This directory attempts to document the ABI between the Linux kernel and userspace, and the relative stability of these interfaces. Due to the everchanging nature of Linux, and the differing maturity levels, these interfaces should be used by userspace programs in different ways. We have four different levels of ABI stability, as shown by the four different subdirectories in this location. Interfaces may change levels of stability according to the rules described below. The different levels of stability are: stable/ This directory documents the interfaces that the developer has defined to be stable. Userspace programs are free to use these interfaces with no restrictions, and backward compatibility for them will be guaranteed for at least 2 years. Most interfaces (like syscalls) are expected to never change and always be available. testing/ This directory documents interfaces that are felt to be stable, as the main development of this interface has been completed. The interface can be changed to add new features, but the current interface will not break by doing this, unless grave errors or security problems are found in them. Userspace programs can start to rely on these interfaces, but they must be aware of changes that can occur before these interfaces move to be marked stable. Programs that use these interfaces are strongly encouraged to add their name to the description of these interfaces, so that the kernel developers can easily notify them if any changes occur (see the description of the layout of the files below for details on how to do this.) obsolete/ This directory documents interfaces that are still remaining in the kernel, but are marked to be removed at some later point in time. The description of the interface will document the reason why it is obsolete and when it can be expected to be removed. removed/ This directory contains a list of the old interfaces that have been removed from the kernel. Every file in these directories will contain the following information: What: Short description of the interface Date: Date created KernelVersion: Kernel version this feature first showed up in. Contact: Primary contact for this interface (may be a mailing list) Description: Long description of the interface and how to use it. Users: All users of this interface who wish to be notified when it changes. This is very important for interfaces in the "testing" stage, so that kernel developers can work with userspace developers to ensure that things do not break in ways that are unacceptable. It is also important to get feedback for these interfaces to make sure they are working in a proper way and do not need to be changed further. Note: The fields should be use a simple notation, compatible with ReST markup. Also, the file **should not** have a top-level index, like:: === foo === How things move between levels: Interfaces in stable may move to obsolete, as long as the proper notification is given. Interfaces may be removed from obsolete and the kernel as long as the documented amount of time has gone by. Interfaces in the testing state can move to the stable state when the developers feel they are finished. They cannot be removed from the kernel tree without going through the obsolete state first. It's up to the developer to place their interfaces in the category they wish for it to start out in. Notable bits of non-ABI, which should not under any circumstances be considered stable: - Kconfig. Userspace should not rely on the presence or absence of any particular Kconfig symbol, in /proc/config.gz, in the copy of .config commonly installed to /boot, or in any invocation of the kernel build process. - Kernel-internal symbols. Do not rely on the presence, absence, location, or type of any kernel symbol, either in System.map files or the kernel binary itself. See Documentation/process/stable-api-nonsense.rst.
