Subject: [PATCH v2 net-next 0/6] net: Random cleanup for netns initialisation.

patch 1 & 2 suppress unwanted memory allocation for net->gen->ptr[].

patch 3 ~ 6 move part of netns initialisation to prenet_init() that
do not require pernet_ops_rwsem.


v2:
  patch 1 : Removed Fixes: tag
  patch 2 : Use XOR for WARN_ON()

v1: https://lore.kernel.org/netdev/20240729210801.16196-1-kuniyu@amazon.com/


Kuniyuki Iwashima (6):
  l2tp: Don't assign net->gen->ptr[] for pppol2tp_net_ops.
  net: Don't register pernet_operations if only one of id or size is
    specified.
  net: Initialise net->passive once in preinit_net().
  net: Call preinit_net() without pernet_ops_rwsem.
  net: Slim down setup_net().
  net: Initialise net.core sysctl defaults in preinit_net().
