#     Merge branch 'next-integrity' of git://git.kernel.org/pub/scm/linux/kernel/git/zohar/linux-integrity
#     
#     Pull integrity updates from Mimi Zohar:
#      "The major feature in this time is IMA support for measuring and
#       appraising appended file signatures. In addition are a couple of bug
#       fixes and code cleanup to use struct_size().
#     
#       In addition to the PE/COFF and IMA xattr signatures, the kexec kernel
#       image may be signed with an appended signature, using the same
#       scripts/sign-file tool that is used to sign kernel modules.
#     
#       Similarly, the initramfs may contain an appended signature.
#     
#       This contained a lot of refactoring of the existing appended signature
#       verification code, so that IMA could retain the existing framework of
#       calculating the file hash once, storing it in the IMA measurement list
#       and extending the TPM, verifying the file's integrity based on a file
#       hash or signature (eg. xattrs), and adding an audit record containing
#       the file hash, all based on policy. (The IMA support for appended
#       signatures patch set was posted and reviewed 11 times.)
#     
#       The support for appended signature paves the way for adding other
#       signature verification methods, such as fs-verity, based on a single
#       system-wide policy. The file hash used for verifying the signature and
#       the signature, itself, can be included in the IMA measurement list"
#     
#     * 'next-integrity' of git://git.kernel.org/pub/scm/linux/kernel/git/zohar/linux-integrity:
#       ima: ima_api: Use struct_size() in kzalloc()
