Minimal supplement to upstream Kernel Self Protection Project changes. Features already provided by SELinux + Yama and archs other than multiarch arm64 / x86_64 aren't in scope. Only tags have stable history. Shared IRC channel with KSPP: irc.libera.chat #linux-hardening

raid5 cache could write bitmap superblock before bitmap superblock is initialized. The bitmap superblock is less than 512B. The current code will only copy the superblock to a new page and write the whole 512B, which will zero the the data after the superblock. Unfortunately the data could include bitmap, which we should preserve. The patch will make superblock read do 4k chunk and we always copy the 4k data to new page, so the superblock write will old data to disk and we don't change the bitmap.

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.
