This is consistent with the GRUB filesystem code in general -which just does a best effort to access the filesystem's data. - -The checksum seed incompat feature has to be removed from the ignore -list if the support for metadata checksum verification is added to the -GRUB ext2 driver later. - -Suggested-by: Eric Sandeen -Suggested-by: Lukas Czerner -Signed-off-by: Javier Martinez Canillas -Reviewed-by: Lukas Czerner -Reviewed-by: Daniel Kiper ---- - grub-core/fs/ext2.c | 10 ++++++++-- - 1 file changed, 8 insertions(+), 2 deletions(-) - -diff --git a/grub-core/fs/ext2.c b/grub-core/fs/ext2.c -index e7dd78e..4953a15 100644 ---- a/grub-core/fs/ext2.c -+++ b/grub-core/fs/ext2.c -@@ -103,6 +103,7 @@ GRUB_MOD_LICENSE ("GPLv3+"); - #define EXT4_FEATURE_INCOMPAT_64BIT 0x0080 - #define EXT4_FEATURE_INCOMPAT_MMP 0x0100 - #define EXT4_FEATURE_INCOMPAT_FLEX_BG 0x0200 -+#define EXT4_FEATURE_INCOMPAT_CSUM_SEED 0x2000 - #define EXT4_FEATURE_INCOMPAT_ENCRYPT 0x10000 - - /* The set of back-incompatible features this driver DOES support.
