Sysdig is open source, system-level exploration:
capture system state and activity from a running Linux
instance, then save, filter and analyze.
Signed-off-by: Angelo Compagnucci <angelo.compagnucci@gmail.com>

Changes v8 -> v9:
- Added SYSDIG_MAKE_ENV to correctly compile kernel driver (thanks Ryan Barnett)
- Added an explicit SYSDIG_POST_INSTALL_TARGET_HOOKS for installing kernel driver
as stated in the official documentation [1]
- Fixed jsoncpp dependency
- The patch should be in a good final shape now
[1] https://github.com/draios/sysdig/wiki/How%20to%20Install%20Sysdig%20from%20the%20Source%20Code
Changes v7 -> v8:
- sysdig now alphabetically ordered in Config.in
Changes v6 -> v7:
- Fixing a nasty mistake in Config.in
Changes v5 -> v6:
- Patching kernel module makefile to be compatible with buildroot.
- Patching cmakefile to remove unneed installation of DKMS infrastructure.
- Removing of unneeded post installation script.
- Added -DUSE_BUNDLED_JSONCPP = NO
- Package is now at the bare minimum.
Changes v4 -> v5:
- Adjusted to 80 columns for sysdig.mk header
Changes v3 -> v4:
- Changed "depends on" to "select" and fixed selected packages
dependencies.
- moved "comment" section to the bottom
Changes v2 -> v3:
- Changed "depends on" and "select" to simplify package
Changes v1 -> v2:
- Changed "depends on" with "select" for dependencies (suggested by Baruch)
- Added comment "sysdig needs a Linux kernel to be built" (suggested by Baruch)
- Upgreded to recently released 0.1.99

It would be good to carry forward previous reviews when you submit a
new version of a patch. In your v8 of this patch Yegor Yefremov
reviewed your patch so after your Signed-off-by line you should put
this:

I have a found a few other things when testing v9 and I have listed them below.

When you have a toolchain that doesn't have one of the required
dependencies, this comment doesn't show up. This is due to have 3
separate depends. Instead the depends should look like this:
comment "sysdig needs a toolchain w/ C++ and a Linux kernel to be built"
depends on !BR2_LINUX_KERNEL || !BR2_INSTALL_LIBSTDCPP \
|| !BR2_PACKAGE_LUAJIT_ARCH_SUPPORTS
(Note indentation above should be tabs instead of spaces)

With these final fixups I think we are about done with some issues. I
will look for you v10

Are you sure? IMO, If the patch changes it should be reviewed again.

Good catch, but the message should be viewed only on supported arhcs,
so it should be:
comment "sysdig needs a toolchain w/ C++ and a Linux kernel to be built"
depends on !BR2_LINUX_KERNEL || !BR2_INSTALL_LIBSTDCPP
depends on BR2_PACKAGE_LUAJIT_ARCH_SUPPORTS

You do bring up a good point. However, I was basing this on what Yann
did with his hash improvement series:

Yes I agree with this.

It basically depends on how much you still changed after that reviewed-by was
given. In this case, it indeed probably changed too much to keep the tag.
For Yegor's convenience, however, it could be good to add something like:
Previous-version-reviewed-by: ...
(At least in my case, I tend to look more carefully at the patches I reviewed
before, and I tend to forget which ones I reviewed in the past.)
Regards,
Arnout
