From 18edfb2af6e7040e0453c84796416be2b8f45454 Mon Sep 17 00:00:00 2001 From: Otavio Salvador Date: Tue, 26 Sep 2017 17:43:55 -0300 Subject: lttng-modules: Backport fixes for kernel instrumentation This backport fixes from upcoming 2.9.4 release. Those are: - Fix: vmalloc wrapper on kernel < 2.6.38 - Fix: vmalloc wrapper on kernel >= 4.12 - Add kmalloc failover to vmalloc - Fix: mmap: caches aliased on virtual addresses - Fix: update ext4 instrumentation for kernel 4.13 - Fix: Sleeping function called from invalid context - Fix: sched for v4.11.5-rt1 - Fix: handle missing ftrace header on v4.12 This fix failures in some BSP layers which are using Linux 4.13 already.
