Subject: [PATCH 02/25] fscrypt: switch from ->is_encrypted() to IS_ENCRYPTED()
Date: Wed, 20 Sep 2017 15:45:42 -0700 [thread overview]
Message-ID: <20170920224605.22030-3-ebiggers3@gmail.com> (raw)
In-Reply-To: <20170920224605.22030-1-ebiggers3@gmail.com>
From: Eric Biggers <ebiggers@google.com>
IS_ENCRYPTED() now gives the same information as
i_sb->s_cop->is_encrypted() but is more efficient, since IS_ENCRYPTED()
is just a simple flag check. Prepare to remove ->is_encrypted() by
switching all callers to IS_ENCRYPTED().
