Subject: [PATCH v2 net-next 00/14] rtnetlink: Refactor rtnl_{new,del,set}link() for per-netns RTNL.
This is a prep for the next series where we will push RTNL down to
rtnl_{new,del,set}link().
That means, for example, __rtnl_newlink() is always under RTNL, but
rtnl_newlink() has a non-RTNL section.
As a prerequisite for per-netns RTNL, we will move netns validation
(and RTNL-independent validations if possible) to that section.
rtnl_link_ops and rtnl_af_ops will be protected with SRCU not to
depend on RTNL.
Changes:
v2:
* Add Eric's Reviewed-by to patch 1-4,6,8-11, (no tag on 5,7,12-14)
* Patch 7
* Handle error of init_srcu_struct().
* Call cleanup_srcu_struct() after synchronize_srcu().
* Patch 12
* Move put_net() before errorout label
* Patch 13
* Newly added as prep for patch 14
* Patch 14
* Handle error of init_srcu_struct().
* Call cleanup_srcu_struct() after synchronize_srcu().
v1: https://lore.kernel.org/netdev/20241009231656.57830-1-kuniyu@amazon.com/
