mainlining shenanigans
c362a06e96
assigning a dummy value of 'clock_id' to avoid cancellation of the cycle
timer before its initialization was a temporary solution, and we still
need to handle the case where act_gate timer parameters are changed by
commands like the following one:
# tc action replace action gate <parameters>
the fix consists in the following items:
1) remove the workaround assignment of 'clock_id', and init the list of
entries before the first error path after IDR atomic check/allocation
2) validate 'clock_id' earlier: there is no need to do IDR atomic
check/allocation if we know that 'clock_id' is a bad value
3) use a dedicated function, 'gate_setup_timer()', to ensure that the
timer is cancelled and re-initialized on action overwrite, and also
ensure we initialize the timer in the error path of tcf_gate_init()
v3: improve comment in the error path of tcf_gate_init() (thanks to
Vladimir Oltean)
v2: avoid 'goto' in gate_setup_timer (thanks to Cong Wang)

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.
