Subject: [PATCH] fix: run john stress in parallel per GPU, fix chromium
 fullscreen, filter BMC virtual disks
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- bee-john-gpu-stress: spawn one john process per OpenCL device in parallel
  so all GPUs are stressed simultaneously instead of only device 1
- bee-openbox-session: --start-fullscreen → --start-maximized to fix blank
  white page on first render in fbdev environment
- storage collector: skip Virtual HDisk* devices reported by BMC/iDRAC
