Subject: [RFC] fscrypt_key_required mount option
Date: Thu, 14 Mar 2019 18:15:55 +0100 [thread overview]
Message-ID: <20190314171559.27584-1-richard@nod.at> (raw)
In-Reply-To: <CAJfpegvX4ANfso-Jn1zaB+m4Q_0eK9i-+MCJ+sTH5QzD3PZFMQ@mail.gmail.com>
This series is an RFC, it outlines how an filesystem, in this case UBIFS,
could implement a mount option to disable filesystem operations on encrypted
files where no key is present.
The desired byproduct is that in this case ->d_revalidate() is not needed
anymore and VFS folks are in less fear about the dcache implications.
Thanks,
//richard
