From 9ed5b01a36a0e40a7450b8a5caf82e0552c41bb3 Mon Sep 17 00:00:00 2001 From: Dmitry Safonov <dima@arista.com> Date: Mon, 8 Jun 2020 21:32:13 -0700 Subject: [PATCH] x86/amd_gart: print stacktrace for a leak with KERN_ERR It's under CONFIG_IOMMU_LEAK option which is enabled by debug config. Likely the backtrace is worth to be seen - so aligning with log level of error message in iommu_full().
