Do you agree on this?</p> <p>Hi Shuichi,</p> <p>I think 4.12 will not be a LTS version kernel for Linux distribution!</p> <p>I did the job for this version because it was the latest vanilla when we wanted to improve Lustre performance.</p> <p>Yes i agree, your team can rebase theses patches to support 4.14 or 4.15 kernel.</p> <p>Moreover, it will be nice to wait for some reviewers (to avoid "overwork" on your side).</p> <p>We are now several version ahead of this <img class="emoticon" src="https://jira.whamcloud.com/images/icons/emoticons/smile.png" height="16" width="16" align="absmiddle" alt="" border="0"/> Will keep patch around for reference for newer vanilla kernel support</p> Related LU-9679 LU-11071 Development Epic/Theme Kernel ldiskfs Rank 1|hzzw8n: Rank (Obsolete) 9223372036854775807
