Subject: [PATCH -next v3 0/7] limit the number of plugged bio

From: Yu Kuai <yukuai3@...wei.com>

Changes in v3:
 - prefix function with 'raid1_' instead of 'md_'
 - use a globle workequeue instead of per bitmap in patch 5
Changes in v2:
 - remove the patch to rename raid1-10.c

Yu Kuai (7):
  md/raid10: prevent soft lockup while flush writes
  md/raid1-10: factor out a helper to add bio to plug
  md/raid1-10: factor out a helper to submit normal write
  md/raid1-10: submit write io directly if bitmap is not enabled
  md/md-bitmap: add a new helper to unplug bitmap asynchrously
  md/raid1-10: don't handle pluged bio by daemon thread
  md/raid1-10: limit the number of plugged bio
