The core sched implementation checks independently for NOLOCK flag to acquire/release the root spin lock and for qdisc_is_percpu_stats() to account per CPU values in many places. This change update the last few places checking the TCQ_F_NOLOCK to do per CPU stats accounting according to qdisc_is_percpu_stats() value. The above allows to clean dev_requeue_skb() implementation a bit and makes stats update always consistent with a single flag. v1 -> v2: - do not move qdisc_is_empty definition, fix build issue Signed-off-by: Paolo Abeni <pabeni@redhat.com> Signed-off-by: David S.

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.
