Patch series "initramfs: "crc" cpio format and INITRAMFS_PRESERVE_MTIME", v7. This patchset does some minor initramfs refactoring and allows cpio entry mtime preservation to be disabled via a new Kconfig INITRAMFS_PRESERVE_MTIME option. Patches 4/6 to 6/6 implement support for creation and extraction of "crc" cpio archives, which carry file data checksums. Basic tests for this functionality can be found at https://github.com/rapido-linux/rapido/pull/163 This patch (of 6): do_header() is called for each cpio entry and fails if the first six bytes don't match "newc" magic. The magic check includes a special case error message if POSIX.1 ASCII (cpio -H odc) magic is detected. This special case POSIX.1 check can be nested under the "newc" mismatch code path to avoid calling memcmp() twice in a non-error case.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
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.
