Pull vfs hardening update from Christian Brauner:
 "Jan pointed out that during shutdown both filp_close() and super block
  destruction will use basic printk logging when bugs are detected. This
  causes issues in a few scenarios:

   - Tools like syzkaller cannot figure out that the logged message
     indicates a bug.

   - Users that explicitly opt in to have the kernel bug on data
     corruption by selecting CONFIG_BUG_ON_DATA_CORRUPTION should see
     the kernel crash when they did actually select that option.

   - When there are busy inodes after the superblock is shut down later
     access to such a busy inodes walks through freed memory. It would
     be better to cleanly crash instead.

  All of this can be addressed by using the already existing
  CHECK_DATA_CORRUPTION() macro in these places when kernel bugs are
  detected. Its logging improvement is useful for all users.

  Otherwise this only has a meaningful behavioral effect when users do
  select CONFIG_BUG_ON_DATA_CORRUPTION which means this is backward
  compatible for regular users"
