2023-10-03docs: admin-guide: sysctl: fix details of struct dentry_stat_tRandy Dunlap
Commit c8c0c239d5ab moved struct dentry_stat_t to fs/dcache.c but did not update its location in Documentation, so update that now. Also change each struct member from int to long as done in commit 3942c07ccf98. Fixes: c8c0c239d5ab ("fs: move dcache sysctls to its own file") Fixes: 3942c07ccf98 ("fs: bump inode and dentry counters to long") Signed-off-by: Randy Dunlap <rdunlap@infradead.org> Cc: Jonathan Corbet <corbet@lwn.net> Cc: linux-doc@vger.kernel.org Cc: Alexander Viro <viro@zeniv.linux.org.uk> Cc: Christian Brauner <brauner@kernel.org> Cc: linux-fsdevel@vger.kernel.org Cc: Luis Chamberlain <mcgrof@kernel.org> Cc: Arnd Bergmann <arnd@arndb.de> Cc: Glauber Costa <glommer@openvz.org> Acked-by: Christian Brauner <brauner@kernel.org> Signed-off-by: Jonathan Corbet <corbet@lwn.net> Link: https://lore.kernel.org/r/20230923195144.26043-1-rdunlap@infradead.org
2022-10-19docs: sysctl/fs: re-order, prettifyStephen Kitt
This brings the text markup in line with sysctl/abi and sysctl/kernel: * the entries are ordered alphabetically * the table of contents is automatically generated * markup is used as appropriate for constants etc. The content isn't fully up-to-date but the obsolete entries are gone, so remove the kernel version mention.

2022-10-19docs: sysctl/fs: merge the aio sectionsStephen Kitt
There are two sections documenting aio-nr and aio-max-nr, merge them. I kept the second explanation of aio-nr, which seems clearer to me, along with the effects of the values from the first section.

2020-07-05Replace HTTP links with HTTPS ones: Documentation/admin-guideAlexander A. Klimov
Rationale: Reduces attack surface on kernel devs opening the links for MITM as HTTPS traffic is much harder to manipulate. Deterministic algorithm: For each file: If not .svg: For each line: If doesn't contain `\bxmlns\b`: For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`: If both the HTTP and HTTPS versions return 200 OK and serve the same content: Replace HTTP with HTTPS.
