head: d358e5254674b70f34c847715ca509e46eb81e6f
commit: a0e2cb6a90634f3dc80f16e882a683ee5761b0b0 um: Add VFIO-based virtual PCI driver
date: 7 months ago
config: um-randconfig-r121-20251212 (https://download.01.org/0day-ci/archive/20251212/202512122110.ZdyWcFXR-lkp@intel.com/config)
compiler: gcc-14 (Debian 14.2.0-19) 14.2.0
reproduce (this is a W=1 build): (https://download.01.org/0day-ci/archive/20251212/202512122110.ZdyWcFXR-lkp@intel.com/reproduce)
If you fix the issue in a separate patch/commit (i.e. not just a new version of
the same patch/commit), kindly add following tags
