Estimated date/release for end of support of Linux kernel 2.6

Hello, I see that Linux kernel 2.6 is deprecated since 1 year (on April 2018, with Splunk 7.1.0). https://docs.splunk.com/Documentation/Splunk/7.1.0/ReleaseNotes/Deprecatedfeatures#Platform_support I would like to know which future version of Splunk will "remove" this kernel version, and if there is an estimated release date. Regards, Christophe
