Subject: fs/ext2: Ignore checksum seed incompat feature
|
|
|
|
This incompat feature is used to denote that the filesystem stored its
|
|
metadata checksum seed in the superblock. This is used to allow tune2fs
|
|
changing the UUID on a mounted metdata_csum filesystem without having
|
|
to rewrite all the disk metadata. However, the GRUB doesn't use the
|
|
metadata checksum at all. So, it can just ignore this feature if it
|
|
is enabled. 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.
