[Vdo-devel] Question related to kernel

[Sweet Tea Dorminy]

Greetings;

Take a look at the 6.1 branch at https://github.com/dm-vdo/kvdo/tree/6.1,
which I believe does build against kernel 4.4. Your compile log seems to
indicate you downloaded a 6.2 version of VDO from Github, which removed
support for certain older kernel versions.

Let us know if you have more problems!

Thanks!

John Dorminy
