Subject: [PATCH 2/4] ext4: wire up FS_IOC_GET_ENCRYPTION_NONCE
Date: Sat, 14 Mar 2020 13:50:50 -0700	[thread overview]
Message-ID: <20200314205052.93294-3-ebiggers@kernel.org> (raw)
In-Reply-To: <20200314205052.93294-1-ebiggers@kernel.org>

From: Eric Biggers <ebiggers@google.com>

This new ioctl retrieves a file's encryption nonce, which is useful for
testing.  See the corresponding fs/crypto/ patch for more details.
