[NFS-Ganesha-Support] ACL support with NFS-Ganesha V3 and the stability of v4 acl implementation

Hi All, We want to use nfs-ganesha with gluster and we have a requirement to use acl with both v3 and v4. But going through the previous mail archives, I understood that acl is not supported with v3. Is there any chance of acl support with v3 in near future. How easy is to implement this feature in v3. An addition question is regarding the stability of acl with v4. Is there any known issues? Is it ready for using it in the production setup. Any users who consumes acl on v4? Any help is much appreciated, Thanks in advance. Rafi KC
