Can you make the structure generic since it is the same for f2fs and
ext4, which let you drop the code guards?  Unless that becomes a problem for
d_revalidate with fscrypt, it is fine like this.

I keep reading the 'enc' in sb_has_enc_strict_mode() as 'encryption'.  What do
you think about renaming it to sb_has_strict_encoding()?

These comments apply equally to patches 3 and 4.  Other than that,
