Subject: [PATCH] md: Fix the 'failed' count for version-0 superblocks
X-Git-Tag: v2.6.17-rc1~295
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=1be7892fffb45f6017494a88ff68fe84c6de26b4;p=platform%2Fkernel%2Flinux-3.10.git

[PATCH] md: Fix the 'failed' count for version-0 superblocks

We are counting failed devices twice, once of the device that is failed, and
once for the hole that has been left in the array.  Remove the former so
'failed' matches 'missing'.  Storing these counts in the superblock is a bit
silly anyway....
