[Pkg-zfsonlinux-devel] Bug#928118: Full backtrace

[James Youngman]

I built an unstripped version of the source package and re-ran the command
to get a better backtrace.  Here's what I did (from history |less):

  518  1556458834 cd packages/
  519  1556458835 mkdir zfs
  520  1556458837 cd zfs
  521  1556458851 apt source libzfs2linux
  522  1556458859 cd zfs-linux-0.7.12/
  523  1556458914 DEB_BUILD_OPTIONS='nostrip noopt debug' dpkg-buildpackage
-b -uc -us
  524  1556458931 : sudo apt install libattr1-dev libblkid-dev
libselinux1-dev uuid-dev zlib1g-dev
  525  1556458958 apt build-dep libzfs2linux
  526  1556458962 sudo apt build-dep libzfs2linux
  527  1556458977 DEB_BUILD_OPTIONS='nostrip noopt debug' dpkg-buildpackage
-b -uc -us
  528  1556459244 ls -l ..
  529  1556459255 ls -l ../*.deb
  530  1556459282 sudo dpkg -i ../libzfs2linux_0.7.12-1~bpo9+1_amd64.deb
  531  1556459293 sudo dpkg -i ../zfsutils-linux_0.7.12-1~bpo9+1_amd64.deb

Here's the more detailed stack backtrace:
