[lvm-devel] [PATCH 0/2] cmirror patch to improve cluster raid1 performance[v3]

These patches work with dm-log-userspace enhancement.
LVM, device-mapper and cmirrord begin to support
merging mark/flush request(if DM_INTEGRATED_FLUSH is set)
This would increase the write throughput of cluster raid1 
based on my own test.


dongmao zhang (2):
  add integrated_flush support to device-mapper
  cmirrord support DM_INTEGRATED_FLUSH
