[BUG] build fails with newest versions of the linux kernel

Open RakuJa opened this issue 6 months ago • 2 comments

Describe the bug Build fails with newer versions of the kernel because a flag used in the code is at the very least deprecated (I think it's removed but I cannot find where at the moment)

To Reproduce Steps to reproduce the behavior:

  1. Follow the instruction detailed in the README.MD for installation
  2. Execute 'make clean && make && sudo make install'
  3. Build fails

Expected behavior Build should be successful. Removing the problematic line results in the build completing successfully.

Screenshots If applicable, add screenshots to help explain your problem. build fail

Architecture

  • Platform: x86_64
