[lttng-dev] [PATCH] Fix: RHEL 7.2 kvm instrumentation

[Michael Jeanson]

Hi,

This patch does not seem to target master or even 2.8 since the 
LTTNG_RHEL_KERNEL_RANGE macro was modified to take 6 arguments per
RHEL kernel version.

We usually only accept patches targeted at master that are then
backported to supported versions.

Regards,

Michael
