> Enforce a configurable limit on:
> the length of a path component
> the number of names in a directory
> The intention is to prevent a too-long name or a too-full directory. This is
> not about RPC buffers, the length of command lines, etc. There may be good
> reasons for those kinds of limits, but that is not the intended scope of this
> feature. Consequently, a reasonable implementation might be to extend the
> existing quota checker so that it faults the creation of a name that violates
> the limits. This strategy of faulting new creation evades the problem of
> existing names or directories that violate the limits.
