From 434c6691a5af2982f6aa9a0b2fcceb2d0759a90e Mon Sep 17 00:00:00 2001 From: Alexandre Montplaisir Date: Fri, 22 May 2015 14:36:53 -0400 Subject: [PATCH] Fix: Update kmem event for recent Ubuntu kernel Ubuntu backported a patch into their 3.13 (Trusty) branch which changes kmem event definition. Upstream commit https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=99592d598eca62bdbbf62b59941c189176dfc614 first appears in 4.0 (and was later backported to 3.19.2). We already have the proper check for this. This corresponds to Ubuntu commit http://kernel.ubuntu.com/git/ubuntu/ubuntu-trusty.git/commit/?id=d938e4bff1089a1f4757ed94a5cace803c6a363b which was first released with 3.13.0-50.82. This required adding a new check specifically for the Ubuntu version.
