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
