With the addition of the *time_extra fields in the on-disk inode, e2fsck needs
to expand the inode for older filesystems. So i_extra_isize needs to be at least
s_min_extra_isize if the EXT4_FEATURE_RO_COMPAT_EXTRA_ISIZE flag is set. This
bug has been created to track the changes required for e2fsprogs to perform the
inode expansion.

Two things need to be done:
1) Improve support for handling EAs in e2fsprogs. (There is a lot of code
duplication and some functionality like adding/removing EAs is not available in
e2fsck.)
2) Implement the e2fsck_expand_extra_isize() function which may need to relocate
some EAs. (Please see bug 10768 for better description of this.)
