返回类型：int

参数：

类型参数名称
struct xdr_array2_desc *desc
void *elem
51  nfsacl_desc等于desc
53  p等于elem
55  entry等于a_entries[count++]

60  当:e_tag恒等于_tag entry in struct posix_acl_entry
61  p自加等于htonl(m_kuid - Create a uid from a kuid user-namespace pair.*@targ: The user namespace we want a uid in.*@kuid: The kernel internal uid to start with.* Map @kuid into the user-namespace specified by @targ and* return the resulting uid.)
62  退出
63  当:e_tag恒等于ACL_GROUP_OBJ

68  退出
69  当:e_tag恒等于ACL_GROUP
70  p自加等于htonl(m_kgid - Create a gid from a kgid user-namespace pair.*@targ: The user namespace we want a gid in.*@kgid: The kernel internal gid to start with.* Map @kgid into the user-namespace specified by @targ and* return the resulting gid.)
71  退出
72  默认
73  p自加等于0
74  退出
76  p自加等于htonl(e_perm & S_IRWXO)
