A concurrent lookup can find this OPP and increment its\nreference count while it is still uninitialized, leading to refcount\ncorruption and a potential premature free.\n\nFix this by initializing ->kref and ->opp_table before making the OPP\nvisible via list_add(). This ensures any concurrent lookup observes a\nfully initialized object.\n\n[ Viresh: Updated commit log ]",
