    I've split this across the various commits they touch:

    Infrastructure management of the cred security blob
    LSM: Infrastructure management of the file security
    LSM: Infrastructure management of the inode security
    LSM: Infrastructure management of the task security
    LSM: Blob sharing support for S.A.R.A and LandLock

    Based on these changes, I've uploaded the "v4.1", or "Casey is on
    vacation", tree here:
    https://git.kernel.org/pub/scm/linux/kernel/git/kees/linux.git/log/?h=lsm/blob-sharing-v4.1

    I'm going to work on a merged series for the "arbitrary ordering" and
    "blob-sharing" trees next...
