[GIT PULL 13/18 for v7.3] vfs mount

[Christian Brauner]

Hey Linus,

/* Summary */

- Make the legacy mount API notify pollers of propagation changes. Changing
  propagation via change_mnt_propagation() or MOVE_MOUNT_SET_GROUP update the
  propagation relationship of the target mount. Unlike mount_setattr() neither
  path touched the affected mount namespace. So pollers of
  /proc/<pid>/mountinfo were never woken.

- Also remove a redundant panic() in mnt_init().

/* Testing */

No build failures or warnings were observed.
