Subject: kbuild: pkg: use --transform option to prefix paths in tar
From: Masahiro Yamada <yamada.masahiro@xxxxxxxxxxxxx>
[ Upstream commit 2dbc644ac62bbcb9ee78e84719953f611be0413d ]
For rpm-pkg and deb-pkg, a source tar file is created. All paths in
the archive must be prefixed with the base name of the tar so that
everything is contained in the directory when you extract it.
Currently, scripts/package/Makefile uses a symlink for that, and
removes it after the tar is created.
If you terminate the build during the tar creation, the symlink is
left over. Then, at the next package build, you will see a warning
like follows:
ln: '.' and 'kernel-4.14.0+/.' are the same file
It is possible to fix it by adding -n (--no-dereference) option to
the "ln" command, but a cleaner way is to use --transform option
of "tar" command. This option is GNU extension, but it should not
hurt to use it in the Linux build system.
The 'S' flag is needed to exclude symlinks from the path fixup.
Without it, symlinks in the kernel are broken.
