Currently, monitor ring reaping and processing occur in the same loop, which requires holding ring locks until skb processing is complete. However, only the ring reaping part requires the ring lock; the skb processing part does not need it. This approach is problematic because it unnecessarily extends the duration for which the ring locks are held, leading to increased contention and potential backpressure issues. Fix it by holding ring locks only during the reaping phase, as skb processing does not require them. First, reap the monitor destination ring with the ring lock and queue the skbs into an skb list. Then, process the skbs in this list in a separate loop without holding the ring lock.

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.
