Subject: [PATCH v4 06/16] fs-verity: add inode and superblock fields
Date: Thu,  6 Jun 2019 08:51:55 -0700	[thread overview]
Message-ID: <20190606155205.2872-7-ebiggers@kernel.org> (raw)
In-Reply-To: <20190606155205.2872-1-ebiggers@kernel.org>

From: Eric Biggers <ebiggers@google.com>

Analogous to fs/crypto/, add fields to the VFS inode and superblock for
use by the fs/verity/ support layer:

- ->s_vop: points to the fsverity_operations if the filesystem supports
  fs-verity, otherwise is NULL.

- ->i_verity_info: points to cached fs-verity information for the inode
  after someone opens it, otherwise is NULL.

- S_VERITY: bit in ->i_flags that identifies verity inodes, even when
  they haven't been opened yet and thus still have NULL ->i_verity_info.
