kernel version build number in .deb to low by 1. [REGRESSION][BISECTED]

kernel version build number in .deb to low by 1. [REGRESSION][BISECTED]

[Doug Smythies]

Hi,

For my kernel compiles the build number included in resulting .deb files is too low by 1.
Example:

$ uname -a
Linux s15 4.19.0-rc1-stock #488 SMP PREEMPT Mon Aug 27 12:09:05 PDT 2018 x86_64 x86_64 x86_64 GNU/Linux

Observe build number 488 (this is the correct build number, or so I think).

$ dpkg -l | grep 4.19.0-rc1
ii  linux-headers-4.19.0-rc1-stock 4.19.0-rc1-stock-487 amd64 Linux kernel headers for 4.19.0-rc1-stock on amd64
ii  linux-image-4.19.0-rc1-stock   4.19.0-rc1-stock-487 amd64 Linux kernel, version 4.19.0-rc1-stock

$ ls -l ../*4.19.0-rc1*
-rw-rw-r-- 1 doug doug     1907 Aug 27 12:18 ../linux-4.19.0-rc1-stock_4.19.0-rc1-stock-487_amd64.changes
-rw-r--r-- 1 doug doug 11484822 Aug 27 12:16 ../linux-headers-4.19.0-rc1-stock_4.19.0-rc1-stock-487_amd64.deb
-rw-r--r-- 1 doug doug 54224118 Aug 27 12:18 ../linux-image-4.19.0-rc1-stock_4.19.0-rc1-stock-487_amd64.deb
-rw-r--r-- 1 doug doug  1019908 Aug 27 12:16 ../linux-libc-dev_4.19.0-rc1-stock-487_amd64.deb

Observe build number 487.

I bisected the kernel, and the result was:

    kbuild: deb-pkg: split generating packaging and build

    Move debian/ directory generation out of builddeb to a new script,
    mkdebian. The package build commands are kept in builddeb, which
    is now an internal command called from debian/rules.

    With these changes in place, we can now use dpkg-buildpackage from
    deb-pkg and bindeb-pkg removing need for handrolled source/changes
    generation.

    This patch is based on the criticism of the current state of builddeb
    discussed on:

I am not familiar with this stuff and was not able to figure out
a solution to propose a patch to correct it.

In case it is relevant, my compile command was:

time make -j9 olddefconfig bindeb-pkg LOCALVERSION=-stock
