We had discussed using a different comment that more clearly stated why
this is necessary and use the same comment across all the patches
implementing this.

This applies to all 4 patches. The suggestion was in my response to
Patch 1/4 V1:

Otherwise, things look good.

[PATCH 2/4] lttng-tools: Integrated from git repo.

[Zumeng Chen]

This patch intended to integrate the Linux trace toolkit, which
is a suite of tools designed to extract program execution details
from the Linux operating system and interpret them.

lttng-tools 2.0 is currently in pre-release(-pre16), so we have to
update it when official released.

[PATCH 3/4] lttng-modules: from lttng-modules 2.0 git repo.

[Zumeng Chen]

This patch intended to integrate the lttng-modules 2.0 package
containing the kernel tracer modules.
LTTng-modules 2.0 is currently in pre-release (-pre11), so we
have to update it when official released.

lttng-2.0 supports lttng-modules extra builds, which don't need
any patches on Linux kernel vs the previous version of lttng.
As described in README of lttng-modules-2.0, so far, it has been
tested in the latest kernel on x86 32/64-bit, and powerpc 32-bit,
, build tested on ARM. So does yocto kernel, the related tests
on qemux86 and qemuppc has been validated and a build test on
qemuarm passed too with this patcheset.
