Eric Dumazet says: ==================== net: polish skb defer freeing While testing this recently added feature on a variety of platforms/configurations, I found the following issues: 1) A race leading to concurrent calls to smp_call_function_single_async() 2) Missed opportunity to use napi_consume_skb() 3) Need to limit the max length of the per-cpu lists. 4) Process the per-cpu list more frequently, for the (unusual) case where net_rx_action() has mutiple napi_poll() to process per round. ==================== Signed-off-by: David S.

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 Restructured Text 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.
