Subject: [PATCH v7 15/16] ubifs: wire up new fscrypt ioctls
Date: Fri, 26 Jul 2019 15:41:40 -0700 [thread overview]
Message-ID: <20190726224141.14044-16-ebiggers@kernel.org> (raw)
In-Reply-To: <20190726224141.14044-1-ebiggers@kernel.org>
From: Eric Biggers <ebiggers@google.com>
Wire up the new ioctls for adding and removing fscrypt keys to/from the
filesystem, and the new ioctl for retrieving v2 encryption policies.
FS_IOC_REMOVE_ENCRYPTION_KEY also required making UBIFS use
fscrypt_drop_inode().
For more details see Documentation/filesystems/fscrypt.rst and the
fscrypt patches that added the implementation of these ioctls.
