#     
#     Pull fs-verity support from Eric Biggers:
#      "fs-verity is a filesystem feature that provides Merkle tree based
#       hashing (similar to dm-verity) for individual readonly files, mainly
#       for the purpose of efficient authenticity verification.
#     
#       This pull request includes:
#     
#        (a) The fs/verity/ support layer and documentation.
#     
#        (b) fs-verity support for ext4 and f2fs.
#     
#       Compared to the original fs-verity patchset from last year, the UAPI
#       to enable fs-verity on a file has been greatly simplified. Lots of
#       other things were cleaned up too.
#     
#       fs-verity is planned to be used by two different projects on Android;
#       most of the userspace code is in place already. Another userspace tool
#       ("fsverity-utils"), and xfstests, are also available. e2fsprogs and
#       f2fs-tools already have fs-verity support. Other people have shown
#       interest in using fs-verity too.
#     
#       I've tested this on ext4 and f2fs with xfstests, both the existing
#       tests and the new fs-verity tests. This has also been in linux-next
#       since July 30 with no reported issues except a couple minor ones I
#       found myself and folded in fixes for.
#     
#       Ted and I will be co-maintaining fs-verity"
