[PATCHv2 45/50] x86/amd_gart: Print stacktrace for a leak with KERN_ERR

From: Dmitry Safonov
Date: Mon Mar 16 2020 - 10:43:07 EST


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().
