cluster/afr: Delay post-op for fsync
Problem: AFR doesn't delay post-op for fsync fop. For fsync heavy workloads this leads to un-necessary fxattrop/finodelk for every fsync leading to bad performance. Fix: Have delayed post-op for fsync. Add special flag in xdata to indicate that afr shouldn't delay post-op in cases where either the process will terminate or graph-switch would happen. Otherwise it leads to un-necessary heals when the graph-switch/process-termination happens before delayed-post-op completes. Fixes: #1253 Change-Id: I531940d13269a111c49e0510d49514dc169f4577 Signed-off-by: Pranith Kumar K <pkarampu@redhat.com>
