Subject: md: change the initialization value for a spare device spot to MD_DISK_ROLE_SPARE
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=8df72024393cdba2543e55d51297f2b2c4ede46f;p=openwrt%2Fstaging%2Fblogic.git

md: change the initialization value for a spare device spot to MD_DISK_ROLE_SPARE

The value for spare spot of sb->dev_roles is changed from
MD_DISK_ROLE_FAULTY to MD_DISK_ROLE_SPARE to keep align
with the value when the superblock is firstly created in
userspace.
