Subject: [PATCH 2/2] fs-verity: remove unnecessary extern keywords

From: Eric Biggers <>

Remove the unnecessary 'extern' keywords from function declarations.
This makes it so that we don't have a mix of both styles, so it won't be
ambiguous what to use in new fs-verity patches.  This also makes the
code shorter and matches the 'checkpatch --strict' expectation.
