This can be allowed because it should only restrict more per the seccomp docs, and multiple apps use it today.

Block kcmp, procees_vm_readv, process_vm_writev.
All these require CAP_PTRACE, and are only used for ptrace related
actions, so are not useful as we block ptrace.

Component: engine
Whether a shared/slave volume propagation will work or not also depends on
where source directory is mounted on and what are the propagation properties
of that mount point. For example, for shared volume mount to work, source
mount point should be shared. For slave volume mount to work, source mount
point should be either shared/slave.
This patch determines the mount point on which directory is mounted and
checks for desired minimum propagation properties of that mount point. It
errors out of configuration does not seem right.
