First, it allows tune2fs to enable the 'casefold' feature on existing filesystems. Then, it improves e2fsck by allowing it to: - fix entries containing invalid UTF-8 characters - detect duplicated entries By default, invalid filenames are only checked when strict mode is enabled. A new option is therefore added to allow the user to force this verification. This series has been tested by running xfstests, and by manually corrupting the test filesystem using debugfs as well.
