Subject: [PATCH v5 13/16] ext4: wire up new fscrypt ioctls
Date: Thu, 18 Apr 2019 16:29:20 -0700	[thread overview]
Message-ID: <20190418232923.250800-14-ebiggers@kernel.org> (raw)
In-Reply-To: <20190418232923.250800-1-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 ext4_drop_inode() call
fscrypt_drop_inode().

For more details see Documentation/filesystems/fscrypt.rst and the
fscrypt patches that added the implementation of these ioctls.
