From 482664ddba81b3a5404fd083bb9697dfffc0b6a4 Mon Sep 17 00:00:00 2001 From: Martin Brandenburg Date: Fri, 12 Aug 2016 12:02:31 -0400 Subject: orangefs: add features op This is a new userspace operation, which will be done if the client-core version is greater than or equal to 2.9.6. This will provide a way to implement optional features and to determine which features are supported by the client-core. If the client-core version is older than 2.9.6, no optional features are supported and the op will not be done. The intent is to allow protocol extensions without relying on the client-core's current behavior of ignoring what it doesn't understand.
