Eventhough the current documentation explains that the reference count gets incremented by both kref_init() and kref_get(), it is often misunderstood that only one instance of kref_put() is needed in the example code. So let's clarify that a bit. Signed-off-by: Manivannan Sadhasivam <manivannan.sadhasivam@linaro.org> Signed-off-by: Jonathan Corbet <corbet@lwn.net>

This script allows sysctl documentation to be checked against the kernel source code, to identify missing or obsolete entries. Running it against 5.5 shows for example that sysctl/kernel.rst has two obsolete entries and is missing 52 entries.

When there was no parallelism (no top-level -j arg and a pre-1.7 sphinx-build), the argument passed would be empty ("") instead of just being missing, which would (understandably) badly confuse sphinx-build. Fix this by removing the quotes. Reported-by: Rafael J.

There are some issues at the script with regards to :doc: tags: - It doesn't escape files under Documentation/sphinx, leading to false positives; - It doesn't handle root URLs, like :doc:`/x86/boot`; - It doesn't output the file with a bad reference. Address those things, in order to remove false positives from the list of problems. Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org> Signed-off-by: Jonathan Corbet <corbet@lwn.net>

The guide to the kernel dev process documentation, for example, contains references to older kernels and their timelines. In addition, one of the "long term support kernels" listed have since reached EOL, and a new one has been named. This patch brings information/tables up to date. Additionally, some very trivial grammatical errors, unclear sentences, and potentially unsavory diction have been edited.

This updates sysctl/kernel.rst to use ReStructured Text more fully: * the list of files is now the table of contents (old entries with no corresponding sections are added as empty sections for now); * code references and commands are formatted as code, except for function names which end up linked to the appropriate documentation; * links are used to point to other documentation and other sections; * tables are used to make lists of values more readable (as already done for some sections); * in heavily-reworked paragraphs, sentences are wrapped individually, to make future diffs easier to read. The first mention of the kernel version is dropped. The second mention, saying that the document is accurate for 2.2, is preserved for now; I will update that once the document really is accurate for a current kernel release.

There is somehow no description of %c corename format specifier for /proc/sys/kernel/core_pattern. The %c corename format specifier is used by user-space application such as systemd-coredump, so it should be documented. To find where %c is handled in the kernel source code, look at function format_corename() in fs/coredump.c.

Pull new zonefs file system from Damien Le Moal: "Zonefs is a very simple file system exposing each zone of a zoned block device as a file. Unlike a regular file system with native zoned block device support (e.g. f2fs or the on-going btrfs effort), zonefs does not hide the sequential write constraint of zoned block devices to the user. As a result, zonefs is not a POSIX compliant file system. Its goal is to simplify the implementation of zoned block devices support in applications by replacing raw block device file accesses with a richer file based API, avoiding relying on direct block device file ioctls which may be more obscure to developers. One example of this approach is the implementation of LSM (log-structured merge) tree structures (such as used in RocksDB and LevelDB) on zoned block devices by allowing SSTables to be stored in a zone file similarly to a regular file system rather than as a range of sectors of a zoned device. The introduction of the higher level construct "one file is one zone" can help reducing the amount of changes needed in the application while at the same time allowing the use of zoned block devices with various programming languages other than C. Zonefs IO management implementation uses the new iomap generic code. Zonefs has been successfully tested using a functional test suite (available with zonefs userland format tool on github) and a prototype implementation of LevelDB on top of zonefs" * tag 'zonefs-5.6-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/dlemoal/zonefs: zonefs: Add documentation fs: New zonefs file system
