+Subject: [PATCH] Add missing grub-core/extra_deps.lst file in release tarball
+
+A file is missing in the grub-2.12 release tarballs (both .gz and .xz).
+See [1]. The issue was reported in [2] and fixed upstream in [3].
+
+This patch adds the missing file, on top of the release tarball. This
+patch won't apply on upstream git, since the file is present in the
+source repository. Since the issue is fixed upstream in [3], it is
+expected upcoming releases tarballs will include the file.
+
+The file content was fetched from the upstream git repo:
+https://git.savannah.gnu.org/gitweb/?p=grub.git;a=blob_plain;f=grub-core/extra_deps.lst;hb=refs/tags/grub-2.12
