Replace kfree_skb() used in enqueue_to_backlog() with kfree_skb_reason(). The skb rop reason SKB_DROP_REASON_CPU_BACKLOG is introduced for the case of failing to enqueue the skb to the per CPU backlog queue. The further reason can be backlog queue full or RPS flow limition, and I think we needn't to make further distinctions. Signed-off-by: Menglong Dong <imagedong@tencent.com> 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.
