understanding RAID1 conf printout in syslog

Hello

I don't find a documentation of the following syslog lines:

RAID1 conf printout:
--- wd:1 rd:2
disk 0, wo:1, o:1, dev:sda1
disk 1, wo:0, o:1, dev:sdb1

What is the meaning of wd, rd, wo and o ?

Thanks for your help

The only documentation is the source code.

wd == working disks
rd == raid disks
wo == write-only
o == online
