The check script always run fscks after the test. In order to
suppress the fsck complaint, we'll need to add this after the
resize2fs invocation:
_scratch_unmount
$DEBUGFS_PROG -w -R "set_super_value s_reserved_gdt_blocks 0" $SCRATCH_DEV \
>>$seqres.full 2>&1
This resets the s_reserved_gdt_blocks field back to zero, so the fsck
doesn't fail. Which is fine, because the point of the test is to see
whether the kernel dereferences a NULL pointer or not.

The way _fixed_by_kernel_commit works is if the test fails (for any
reason), it prints that you MAY be missing the bugfix commit:
