With bump of package/e2fsprogs to 1.47.0 [1] a freshly generated
ext4 fs has unfortunately different default features enabled
(e.g. metadata_csum_seed). This and some other newer fs features
(e.g. large_dir) are however not supported by our grub2.
Thus, newly generated ext-based rootfs won't be recognized by grub2
and are therefore not bootable/usable from grub2 anymore. This is
an issue already known to other Linux derivates [2],[3],[4].
This commit introduces two additional upstream patches to
package/grub2 which adds EXT4_FEATURE_INCOMPAT_CSUM_SEED and
EXT4_FEATURE_INCOMPAT_LARGEDIR to the EXT2_DRIVER_IGNORED_INCOMPAT
list of ignored incompatible ext features, allowing grub2 to
use ext filesystems with these newer default feature sets.
