Kuniyuki Iwashima says: ==================== rtnetlink: Convert rtnl_newlink() to per-netns RTNL. Patch 1 - 3 removes __rtnl_link_unregister and protect link_ops by its dedicated mutex to move synchronize_srcu() out of RTNL scope. Patch 4 introduces struct rtnl_nets and helper functions to acquire multiple per-netns RTNL in rtnl_newlink(). Patch 5 - 8 are to prefetch the peer device's netns in rtnl_newlink(). Patch 9 converts rtnl_newlink() to per-netns RTNL. Patch 10 pushes RTNL down to rtnl_dellink() and rtnl_setlink(), but the conversion will not be completed unless we support cases with peer/upper/lower devices. I confirmed v3 survived ./rtnetlink.sh; rmmod netdevsim.ko; without lockdep splat. v3: https://lore.kernel.org/20241107022900.70287-1-kuniyu@amazon.com v2: https://lore.kernel.org/20241106022432.13065-1-kuniyu@amazon.com v1: https://lore.kernel.org/20241105020514.41963-1-kuniyu@amazon.com ==================== Link: https://patch.msgid.link/20241108004823.29419-1-kuniyu@amazon.com Signed-off-by: Jakub Kicinski <kuba@kernel.org> |

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
