From: Sergio Gelato <Sergio.Gelato@xxxxxxxxxxx> 3.4.105-rc1 review patch. If anyone has any objections, please let me know. ------------------ BugLink: http://bugs.launchpad.net/bugs/1348670 Fix regression introduced in pre-3.14 kernels by cherry-picking aa07c713ecfc0522916f3cd57ac628ea6127c0ec (NFSD: Call ->set_acl with a NULL ACL structure if no entries). The affected code was removed in 3.14 by commit 4ac7249ea5a0ceef9f8269f63f33cc873c3fac61 (nfsd: use get_acl and ->set_acl). The ->set_acl methods are already able to cope with a NULL argument.
