From: Julia Lawall <julia@xxxxxxx> posix_acl_clone does a memory allocation and sets a reference count, so posix_acl_release is needed afterwards to free it. The problem was fixed using the following semantic patch. (http://www.emn.fr/x-info/coccinelle/) // <smpl> @@ type T; identifier E; expression E1, E2; int ret; statement S; @@ T E; <+...
