Breno Leitao says: ==================== net: netpoll: remove dead code and speed up rtnl-locked region This patchset introduces two minor modernizations to the netpoll infrastructure: The first patch removes the unused netpoll pointer from the netpoll_info structure. This member is redundant and its presence does not benefit multi-instance setups, as reported by Jay Vosburgh. Eliminating it cleans up the structure and removes unnecessary code. The second patch updates the netpoll resource cleanup routine to use synchronize_net() instead of synchronize_rcu(). As __netpoll_free() is always called under the RTNL lock, using synchronize_net() leverages the more efficient synchronize_rcu_expedited() in these contexts, reducing time spent in critical sections and improving performance. Both changes simplify maintenance and enhance efficiency without altering netpoll behavior. ==================== Link: https://patch.msgid.link/20250918-netpoll_jv-v1-0-67d50eeb2c26@debian.org 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.
