* Mon Mar 01 2021 Eugene Syromiatnikov <esyr@redhat.com> 2.0.8-1.3

- Replace "and" with "with" in pre-4.18.0-240.14.1.el8_3 kernel dependency

  to match it more precisely (it passes when both post-4.18.0-240.14.1.el8_3

  and pre-4.18.0-240.el8 kernels installed otherwise).

* Tue Feb 23 2021 Eugene Syromiatnikov <esyr@redhat.com> 2.0.8-1.2

- Build against kernel-4.18.0-240.14.1.el8_3 in addition to GA kernel

  (#1931546).

* Mon Feb 22 2021 Eugene Syromiatnikov <esyr@redhat.com> 2.0.8-1.1

- Check for symvers.gz presence in /lib/modules/KVER in addition to boot.

* Wed Dec 09 2020 Eugene Syromiatnikov <esyr@redhat.com> 2.0.8-1

- 19e841b848491d1e14dcd0063d8d681ed1190255

- oracleasm kernel module

- Resolves: #bz1904159
