Here is another update of the richacl patches. Changes since the last posting (https://lwn.net/Articles/689151/): * Rebase on top of 4.7-rc5+ because of commit 999653786d "nfsd: check permissions when setting ACLs". * Introduce set_richacl() similar to set_posix_acl() and use it in nfsd to avoid going through the richacl xattr representation. The complete patch queue is available here: git://git.kernel.org/pub/scm/linux/kernel/git/agruen/linux-richacl.git \ richacl-2016-06-30 The richacl user-space utilitites, man pages, and test suite are available here: https://github.com/andreas-gruenbacher/richacl Changes to other user-space packages for richacl: https://github.com/andreas-gruenbacher/coreutils https://github.com/andreas-gruenbacher/e2fsprogs https://github.com/andreas-gruenbacher/samba https://github.com/andreas-gruenbacher/xfsprogs-dev https://github.com/andreas-gruenbacher/nfs-utils Please see the richacl homepage for more information: http://www.bestbits.at/richacl/ What more needs to be done to get this initial set of patches merged?
