From ca6a3d1e396a65d25e54d331bef966178cd55375 Mon Sep 17 00:00:00 2001 From: Pranith Kumar K Date: Thu, 28 Mar 2013 11:29:41 +0530 Subject: cluster/afr: piggyback and fsync resume changes 1) pre_op_piggyback should always be decremented. 2) Move fsync resume to just after post_op. 3) fsync stub should be created from afr's local not from the final response.
