From: Eric Biggers <[email protected]>

This is needed to test the encryption and casefolding features in combination.

Yeah, this is has been on my radar screen, but it's been on my todo list to submit a patch to generic/556 something like:

if [ "$FSTYP" = "ext4" -a ! -f /sys/fs/ext4/features/encrypted_casefold ]; then
_notrun "ext4 file system does not support encrypted casefold"
fi

before removing generic/556 from the encrypt.exclude list.

I'll probably get to it by this weekend, unless someone beats me to it.

Cheers,
