Eric Dumazet 3016024d75 net_sched: add back BH safety to tcf_lock
Jamal reported that we had to use BH safety after all,
because stats can be updated from BH handler.

Fixes: 3133d5c15c ("net_sched: remove BH blocking in eight actions")
Fixes: 53df77e785 ("net_sched: act_skbmod: use RCU in tcf_skbmod_dump()")
Fixes: e97ae74297 ("net_sched: act_tunnel_key: use RCU in tunnel_key_dump()")
Fixes: 48b5e5dbdb ("net_sched: act_vlan: use RCU in tcf_vlan_dump()")

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.
