Since 9e3596b0c653 ("kbuild: initramfs cleanup, set target from Kconfig")
"make clean" leaves behind compressed initramfs images. Example:
$ make defconfig
$ sed -i 's|CONFIG_INITRAMFS_SOURCE=""|CONFIG_INITRAMFS_SOURCE="/tmp/ir.cpio"|' .config
$ make olddefconfig
$ make -s
$ make -s clean
$ git clean -ndxf | grep initramfs
Would remove usr/initramfs_data.cpio.gz
clean rules do not have CONFIG_* context so they do not know which
compression format was used. Thus they don't know which files to delete.
Tell clean to delete all possible compression formats.
Once patched usr/initramfs_data.cpio.gz and friends are deleted by
"make clean".

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.
