[PATCH] Show DELAYED, PENDING status of resync process in "--detail"

[PATCH] Show DELAYED, PENDING status of resync process in "--detail"

am 18.06.2011 16:10:35 von krzysztof.wojcik

Initialy there is no proper translation mdstat's DEYALED/PENDING processes
to "--detail" output.
For example, if we have revover=DELAYED in mdstat, "--detail"
shows "State: recovering" and "Rebuild Status = 0%".
It was incorrect in case of process waiting on checkpoint different
than 0%. In fact rebuild status is differnt than 0% and user is misled.

The patch fix the problem. Current "--detail" command shows
in the exampe: "State: recovering (DELAYED)" and no information
about precentage.
