[lvm-devel] [PATCH 0/4] LVM/cmirrord support write improvement.

[dongmao zhang]

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

dongmao zhang (4):
  cmirrord add support_delay_clear option
  cmirrord create new function _clog_flush
  add support_delay_flush to device-mapper
  cluster LVM use flag DM_SUPPORT_DELAY_FLUSH
