UEKr8 doesn't include dm-vdo

[4-cHar]

UEKr8 does not include the dm-vdo module, and kvdo is no longer available in new kernel versions.
both uekR8 and uekR8U1 have this problem, when lvcreate a vdo volume, it could not works:

[root@localhost ~]# pvcreate /dev/sda
  Physical volume "/dev/sda" successfully created.
[root@localhost ~]# vgcreate vg /dev/sda
  Volume group "vg" successfully created
[root@localhost ~]# lvcreate --type vdo -n lv0 -L 10G vg
modprobe: ERROR: could not insert 'dm_vdo': Exec format error
  /usr/sbin/modprobe failed: 1
  vdo: Required device-mapper target(s) not detected in your kernel.
  Run `lvcreate --help' for more information.

env:

[root@localhost ~]# cat /etc/os-release|grep '^NAME\|^VERSION'
NAME="Oracle Linux Server"
VERSION="9.6"
VERSION_ID="9.6"
[root@localhost ~]# uname -r

I'm sorry, you are right. It is question for Oracle Enterprise Linux, not UEK's. Anyway thanks.

I have opened an internal request to review.

UEK does not provide a block compression module similar to VDO. However, unlike RHCK, UEK fully supports the btrfs filesystem in production, and it offers filesystem level compression options.

For documentation on how to use compression on btrfs, see the official documentation here: https://btrfs.readthedocs.io/en/latest/Compression.html
