[PATCH 0/3] Failed array handling improvements

[Mariusz Tkaczyk <mariusz.tkaczyk@linux.intel.com>]

Hi Song,
In v4 following changes were made:
- raid1_error and raid10_error description reworked, suggested by Guoqing.
- Error messages for raid0 and linear reworked, suggested by Guoqing.
- check for sync_request replaced by level checks, suggested by Guoqing.

I did manual (mainly on IMSM) tests, here my next TODOs in mdadm:
- broken state handling for redundant arrays in mdadm (it is exposed in sysfs).
  Currently it is working same as before, because broken is not a case for
  redundant arrays in mdadm. It requires to deal with already defined "FAILED"
  state in mdadm.
- Blocking manual removal of devices (#mdadm --set-faulty).

I run following native mdadm tests with and without changes, all passed:
#./test --disks=/dev/nullb[1-5] --tests=00raid1,00raid4,00raid5,00raid6,01r1fail,
01r5fail,01replace,02r1add,05r1failfast,05r1re-add,05r1re-add-nosuper

Mariusz Tkaczyk (3):
  raid0, linear, md: add error_handlers for raid0 and linear
  md: Set MD_BROKEN for RAID1 and RAID10
  raid5: introduce MD_BROKEN
