[Impact]
 It was discovered that the virtual graphics memory manager implementation
 in the Linux kernel was subject to a race condition, potentially leading
 to an information leak.

[Test case]
reproducer was tested, though no leak could be demonstreated with or
without the fix.

[Potential regression]
vgem driver users may be affected.

Chris Wilson (1):
  drm/vgem: Reclassify buffer creation debug message

Daniel Vetter (1):
  drm/vgem: Close use-after-free race in vgem_gem_create
