[PATCH v15 11/11] fs/ioctl: Add a comment to keep the logic in sync with LSM policies

[Günther Noack]

Landlock's IOCTL support needs to partially replicate the list of
IOCTLs from do_vfs_ioctl().  The list of commands implemented in
do_vfs_ioctl() should be kept in sync with Landlock's IOCTL policies.
