Pull namespace fixes from Eric Biederman:
 "I believe all of these are simple obviously correct bug fixes. These
  fall into two groups:

   - Fixing the implementation of MNT_LOCKED which prevents lesser
     privileged users from seeing unders mounts created by more
     privileged users.

   - Fixing the extended uid and group mapping in user namespaces.

  As well as ensuring the code looks correct I have spot tested these
  changes as well and in my testing the fixes are working"

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace:
  mount: Prevent MNT_DETACH from disconnecting locked mounts
  mount: Don't allow copying MNT_UNBINDABLE|MNT_LOCKED mounts
  mount: Retest MNT_LOCKED in do_umount
  userns: also map extents in the reverse map to kernel IDs

+Description
+-----------
+
+i2c-nvidia-gpu is a driver for I2C controller included in NVIDIA Turing
+and later GPUs and it is used to communicate with Type-C controller on GPUs.
+
+If your 'lspci -v' listing shows something like the following,
+
+01:00.3 Serial bus controller [0c80]: NVIDIA Corporation Device 1ad9 (rev a1)
+
+then this driver should support the I2C controller of your GPU.
