[PATCH RFC 0/3] md/raid1: data corruption with serialization

[Xiao Ni <xni@redhat.com>]

A data corruption can happen when using serialization for raid1.
Serialization is not enabled by default. But it looks like there
is a data corruption risk if serialization is closed. Because the
lower driver can't guarantee the sequence which io is written first.
So it's possible that different member disks will have different
data for nvme devices. This patch set doesn't open serialization
by default.

Xiao Ni (3):
  md: add return value of mddev_create_serial_pool
  md/raid1: fix data corruption by moving serialization to mddev level
  md/raid1: fix incorrect sector range in serialization
