[PATCH v24 00/22] Richacls (Core and Ext4)

From: Andreas Gruenbacher
Date: Mon Jul 25 2016 - 10:09:40 EST


Here is another update of the richacl patches. Changes since the last posting
(https://lwn.net/Articles/693099/):

* Rebase on top of the 4.7 kernel.

* De-union ba_refcount and ba_rcu in struct base_acl (analogous to mainline
commit 6d4e56ce9 from Jeff Layton).

* Functions check_richacl and check_posix_acl moved from fs/namei.c into
fs/richacl.c and fs/posix_acl.c to avoid #ifdefs in the code.

* nfs: Use PTR_ERR_OR_ZERO instead of open-coding it.

* Remove outdated comment for richacl_mode_to_mask. Turn richacl_want_to_mask
into a static function.

* Patch "posix_acl: Improve xattr fixup code" has become unrelated to this
patch queue; move it out of the way.


As always, the complete patch queue is available here:
