Extend tcf_chain with 'flushing' flag. Use the flag to prevent insertion of new classifier instances when chain flushing is in progress in order to prevent resource leak when tcf_proto is created by unlocked users concurrently. Return EAGAIN error from tcf_chain_tp_insert_unique() to restart tc_new_tfilter() and lookup the chain/proto again.

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.
