Kuniyuki Iwashima says: ==================== net: Convert ->exit_batch_rtnl() to ->exit_rtnl(). While converting nexthop to per-netns RTNL, there are two blockers to using rtnl_net_dereference(), flush_all_nexthops() and __unregister_nexthop_notifier(), both of which are called from ->exit_batch_rtnl(). Instead of spreading __rtnl_net_lock() over each ->exit_batch_rtnl(), we should convert all ->exit_batch_rtnl() to per-net ->exit_rtnl() and run it under __rtnl_net_lock() because all ->exit_batch_rtnl() functions do not have anything to factor out for batching. Patch 1 & 2 factorise the undo mechanism against ->init() into a single function, and Patch 3 adds ->exit_batch_rtnl(). Patch 4 ~ 13 convert all ->exit_batch_rtnl() users. Patch 14 removes ->exit_batch_rtnl(). Later, we can convert pfcp and ppp to use ->exit_rtnl(). v1: https://lore.kernel.org/all/20250410022004.8668-1-kuniyu@amazon.com/ ==================== Link: https://patch.msgid.link/20250411205258.63164-1-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.
