Rules are inserted into hash table in accordance with their hash index. When a certain number of rules is reached, the table is rehashed: a bigger new table is allocated and all the rules are moved there. But sometimes a new rule can't be inserted into the hash table because its index is full, even though the number of rules in the table is well below the threshold. The hash function is not perfect, so such cases are not rare. When that happens, we want to do the same rehash, in order to increase the table size and lower the probability for such cases. This patch fixes the usecase where rule insertion was failing, but rehash couldn't be initiated due to low number of rules: it adds flag that denotes that rehash is required, even if the number of rules in the table is below the rehash threshold.

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.
