Linus Torvalds f60c55a94e fs-verity for 5.4
Please consider pulling fs-verity for 5.4.
 
 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.
