From 7cb8982cbbe8298cd1bdd35055f7d3818f4a136f Mon Sep 17 00:00:00 2001 From: Amar Tumballi Date: Wed, 7 Apr 2010 04:19:48 +0000 Subject: backword compatibility with 3.0.x releases - restored * glusterfs.h - added back the removed 'fop' types in same order * call-stub.c - enhanced logging in case of failure * server-protocol.c - added a ENOSYS function for these fops, so there will be no crash if a old client connects to mainline server.
