Subject: [PATCH AUTOSEL 4.19 27/33] kbuild: clean compressed initramfs image
Date: Sun, 29 Sep 2019 13:34:15 -0400	[thread overview]
Message-ID: <20190929173424.9361-27-sashal@kernel.org> (raw)
In-Reply-To: <20190929173424.9361-1-sashal@kernel.org>

From: Greg Thelen <gthelen@google.com>

[ Upstream commit 6279eb3dd7946c69346a3b98473ed13d3a44adb5 ]

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".
