From 140ade7579fb78822566924134d4547c24614d4f Mon Sep 17 00:00:00 2001 From: Michael Jeanson Date: Fri, 5 Feb 2021 15:21:55 -0500 Subject: [PATCH] fix: UTS_UBUNTU_RELEASE_ABI is close to overflow We allocated only 8bits for UTS_UBUNTU_RELEASE_ABI in LTTNG_UBUNTU_KERNEL_VERSION, the current Xenial kernel has an ABI of 207 which is getting close to 256. Bump it to 16bits to avoid breakage in the future.
