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. -- This message is automatically generated by JIRA.
