Subject: [PATCH 3/3] fscrypt: remove unnecessary extern keywords
Date: Mon, 11 May 2020 12:13:58 -0700 [thread overview]
Message-ID: <20200511191358.53096-4-ebiggers@kernel.org> (raw)
In-Reply-To: <20200511191358.53096-1-ebiggers@kernel.org>
From: Eric Biggers <ebiggers@google.com>
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 fscrypt patches. This also makes the code
shorter and matches the 'checkpatch --strict' expectation.
