the + should not be a problem. I've created a small test bed using the
version comparission from needrestart (which is based on Sort::Naturally):

$VAR1 = [
          '4.20.0-rc6-tp520-btrfs-trim+',
          '4.20.0',
          '4.19.0-rc6-tp520-btrfs-trim+',
          '4.19.0',
          '4.10',
          '3.19.3-rc6-tp520-btrfs-trim+',
          '3.19.3',
          '3.19.0-rc7-tp520+',
          '3.10',
          '4.9',
          '4.4.0-foo',
          '4.4.0',
          '4.0.0-rc6-tp520-btrfs-trim+',
          '4.0.0',
          '4.0',
          '3.9',
          '3.3',
          '2.6'
        ];

The expected kernel version reported by needrestart is the first one...
I need to review why i.e. 4.9 looses against 3.10.


Thanks for reporting,
Thomas
