Description: Recognize ext2/3/4 filesystem features
|
|
metdata_csum_seed and large_dir; ignore them as
|
|
they are not used by GRUB and can be safely
|
|
ignored, instead of treat these unrecognized
|
|
features as hard errors. Particularly, the
|
|
metadata_csum_seed feature is enabled by
|
|
e2fsprogs >= 1.47.0, so failing to recognize it
|
|
will cause grub-install failure if the /boot
|
|
partition (or /, when /boot is not a separate
|
|
partition) is created by a recent mkfs.ext4.

Subject: [PATCH] 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.

Subject: [PATCH] fs/ext2: Ignore the large_dir incompat feature
|
|
|
|
Recently, ext4 added the large_dir feature, which adds support for
|
|
a 3 level htree directory support.
|
|
|
|
The GRUB supports existing file systems with htree directories by
|
|
ignoring their existence, and since the index nodes for the hash tree
|
|
look like deleted directory entries (by design), the GRUB can simply do
|
|
a brute force O(n) linear search of directories. The same is true for
|
|
3 level deep htrees indicated by large_dir feature flag.
|
|
|
|
Hence, it is safe for the GRUB to ignore the large_dir incompat feature.
