From: Kienan Stewart Date: Fri, 22 Mar 2024 13:28:08 +0000 (-0400) Subject: Fix: build kvm probe on EL 8.4+ X-Git-Tag: v2.13.13~20 X-Git-Url: https://git.lttng.org./?a=commitdiff_plain;h=578ab2074b3eea0b0e18054f83ccb1cc4dc7df23;p=lttng-modules.git Fix: build kvm probe on EL 8.4+ The lower value of the EL range, 240.15.1, corresponds to the first import of EL r8 kernels into Rocky Linux's kernel staging repo. The change may have been introduced in an earlier RHEL 8 kernel, prior to the history of imports into Rocky.
