glibc 2.28-0ubuntu1 ADT test failure with linux 5.0.0-1.2

Due to scripts/check-installed-headers.sh using a regex to search for obsolete types.

  obsolete_type_re=\
  '\<((__)?(quad_t|u(short|int|long|_(char|short|int([0-9]+_t)?|long|quad_t))))\>'
  ...
  if grep -qE "$obsolete_type_re" "$h"; then
      echo "*** Obsolete types detected:"
      grep -HE "$obsolete_type_re" "$h"
      failed=1
  fi

This is catching a string in a comment:

  KERN_PANIC_PRINT=78, /* ulong: bitmask to print system info on panic */

The test needs to be fixed.

Proposed fix:

This bug is missing log files that will aid in diagnosing the problem. While running an Ubuntu kernel (not a mainline or third-party kernel) please enter the following command in a terminal window:

apport-collect 1813060

and then change the status of the bug to 'Confirmed'.

If, due to the nature of the issue you have encountered, you are unable to run this command, please add a comment stating that fact and change the bug status to 'Confirmed'.

This change has been made by an automated script, maintained by the Ubuntu Kernel Team.

We've applied a patch temporarily to replace ulong in the comment with unsigned long to avoid having glibc tests broken in ADT. Once the glibc test has been updated we can revert the patch in the kernel.

This bug was fixed in the package linux - 5.0.0-7.8
