below. The policy does not apply to non-Intel (C) notices.
git log --follow -C90% --format=%ad --date default <file> | tail -1
and then pull just the 4 digit year from the result.
Intel copyrights were not added to files where Intel either had
no contribution ot the contribution lacked substance (ie license
header updates, formatting changes, etc). Contribution date used
"--follow -C95%" to get the most accurate date.
Note that several files in this patch didn't end the license/(c)
block with a blank comment line so these were added as the vast
majority of files do have this last blank line. Simply there for
consistency.

(84ab68c) test/scheduler: add a for_each_reactor shutdown test
Patch above added regression test for handling spdk_for_each_reactor
during shutdown, by adding constant repeat of this operation
while application is running.
Reactor event processing (especially constant) has impact on the
reactor_interrupt_run(). spdk_fd_group_wait() will almost always
execute an event, skewing the results of scheduler test.
Reactor that should have been idle, will show active usage via
/proc/stat.
Fixes#1950
This patch makes this regression test optional, and enables it
only in test that does not measure CPU utilization from the system.
The ./test/event/scheduler/scheduler.sh is the only one where it is
enabled, as it's purpose is to verify the test scheduler application.
Remaining ./test/scheduler/*.sh tests do verify CPU utilization,
so the regression test is disabled in those.
Modified the for_each_done, to for_each_reactor_start, to better
reflect the intention.
On my system enabling spdk_for_each_reactor test flag on the
scheduler application with no threads (except app thread),
consumes ~20-25% CPU from every core in CPU mask.
Meanwhile disabling it, idle cores are 100% idle
and active cores spend 100% of CPU time in usr.

Many open source projects have moved to using SPDX identifiers
to specify license information, reducing the amount of
boilerplate code in every source file. This patch replaces
the bulk of SPDK .c, .cpp and Makefiles with the BSD-3-Clause
identifier.
Almost all of these files share the exact same license text,
and this patch only modifies the files that contain the
most common license text. There can be slight variations
because the third clause contains company names - most say
"Intel Corporation", but there are instances for Nvidia,
Samsung, Eideticom and even "the copyright holder".
Used a bash script to automate replacement of the license text
with SPDX identifier which is checked into scripts/spdx.sh.

The scheduler test app is ideal for testing that the
reactors properly flush any existing for_each_reactor
operations during the shutdown process. This is
because it has no SPDK subsystems, so the reactors
stop immediately after the application is signaled to
terminate.
So start a for_each_reactor operation when the
application starts, and then keep starting another
one once the previous one completes.
This serves as a regression test for issue #2206.

Now a test thread will have one idle_poller and an optional
busy poller (when active_percent > 0).
The idle poller will just consume a very small amount of
tsc via spdk_delay_us(10).
If active_percent > 0, we will start a timed poller for
TIMESLICE_US (currently 100 * 1000). When that timer
expires, it will consume TIMESLICE_US * active_percent
microseconds.
I think this is a slightly simpler way to enforce the
thread consumption percentages specified by the tests.

So far the test application was mostly used for cases with
single active thread on a core.
Setting activity as percentage of all poller operations worked
fine for those cases.
This patch changes the thread activity to mean percentage of
a set time period.
Which equals to the maximum load a thread will see when being
alone on the core.
Right now g_core_time_period is set to 100ms, and is the
maximum execution time for all threads on a core when
thread activity is set to 100%.
g_timeslice is set to 100us and is the execution time of
single thread poll.
Consider following scenario:
Before the patch
Thread1 Activity 70% Busy 70 Idle 30 Load 70%
Thread2 Activity 60% Busy 60 Idle 40 Load 60%
Core Busy 130 Idle 70 Load 65%
After the patch
Thread1 Activity 70% Busy 100 Idle 0 Load 100%
Thread2 Activity 60% Busy 100 Idle 0 Load 100%
Core Busy 200 Idle 0 Load 100%
Additionally increased period of sleeping from 1us to 100us,
to offset the time needed for additional operations
during thread poll.

This is an application designed to provide custom RPC
interface for testing scheduler and governor implementations.
Based on those RPCs scenarios later can be implemented to verify
