Without rtnl lock protection masks with same key can be inserted concurrently. Insert temporary mask with reference count zero to masks hashtable. This will cause any concurrent modifications to retry. Wait for rcu grace period to complete after removing temporary mask from masks hashtable to accommodate concurrent readers.

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.
