The branch, v3-6-test has been updated via 06a02e2 Split the ACE flag mapping between nfs4 and Windows into two separate functions rather than trying to do it inline. Allows us to carefully control what flags are mapped to what in one place. Modification to bug #8191 - vfs_gpfs dosn't honor ACE_FLAG_INHERITED_ACE via 009ceea nfs4_acls: pass ACE_FLAG_INHERITED_ACE down from the client via ab1fd07 nfs4_acls: pass ACE_FLAG_INHERITED_ACE up to the client from d6b991a s3-docs: Fix version.
