Bug#488235: ext2.mod should reject extN with INCOMPAT flags which grub doestn't support

[Felix Zielcke]

retitle 488235 ext2.mod should reject extN with INCOMPAT flags which grub doestn't support
thanks

For me the original issue is now fixed, ext2.mod has now extents support
but this has now been discussed at grub-devel
grub should reject an extN based filesystem where incompatibly flags are set which grub can't handle.
