Stanislav Fomichev says: ==================== net: Convert to skb_dstref_steal and skb_dstref_restore To diagnose and prevent issues similar to [0], emit warning (CONFIG_DEBUG_NET) from skb_dst_set and skb_dst_set_noref when overwriting non-null reference-counted entry. Two new helpers are added to handle special cases where the entry needs to be reset and restored: skb_dstref_steal/skb_dstref_restore. The bulk of the patches in the series converts manual _skb_refst manipulations to these new helpers. 0: https://lore.kernel.org/netdev/20250723224625.1340224-1-sdf@fomichev.me/T/#u ==================== Link: https://patch.msgid.link/20250818154032.3173645-1-sdf@fomichev.me 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.
