Subject: [PATCH 0/7] KVM: Grab KVM references for stats fds

Grab a reference to the VM when handing a userspace stats fds for VMs and
vCPUs to ensure the stats files don't outlive the VM and its vCPUs, and add
a regression testcase in selftests.

Sean Christopherson (7):
  KVM: Grab a reference to KVM for VM and vCPU stats file descriptors
  KVM: selftests: Use pread() to read binary stats header
  KVM: selftests: Clean up stats fd in common stats_test() helper
  KVM: selftests: Explicitly free vcpus array in binary stats test
  KVM: selftests: Verify userspace can create "redundant" binary stats
    files
  KVM: selftests: Verify stats fd can be dup()'d and read
  KVM: selftests: Verify stats fd is usable after VM fd has been closed
