Subject: [PATCH v3 0/3] ovl: Fix null ptr dereference at realinode in rcu-walk

v1->v2:
  Extract a helper to get realpath and real inode from ovl inode.
  Get realinode from realpath in do_ovl_get_acl().
v2->v3:
  Modify original helper ovl_i_path_real() to return the realinode.

Zhihao Cheng (3):
  ovl: Let helper ovl_i_path_real() return the realinode
  ovl: ovl_permission: Fix null pointer dereference at realinode in
    rcu-walk mode
  ovl: get_acl: Fix null pointer dereference at realinode in rcu-walk
    mode
