[PATCH 4.16 47/64] x86/vector: Fix the args of vector_alloc tracepoint
From: Greg Kroah-Hartman
Date: Sun Jun 24 2018 - 11:36:39 EST
4.16-stable review patch. If anyone has any objections, please let me know.
------------------
From: Dou Liyang <douly.fnst@xxxxxxxxxxxxxx>
commit 838d76d63ec4eaeaa12bedfa50f261480f615200 upstream.
The vector_alloc tracepont reversed the reserved and ret aggs, that made
the trace print wrong. Exchange them.
Fixes: 8d1e3dca7de6 ("x86/vector: Add tracepoints for vector management")
