Revision 6d3baf2eb8bd680b2d4f509bc3dbf4dcd6e27a40 authored by NeilBrown on 05 March 2007, 08:30:44 UTC, committed by Linus Torvalds on 05 March 2007, 15:57:53 UTC
Recent patch for raid6 reshape had a change missing that showed up in subsequent review. Many places in the raid5 code used "conf->raid_disks-1" to mean "number of data disks". With raid6 that had to be changed to "conf->raid_disk - conf->max_degraded" or similar. One place was missed. This bug means that if a raid6 reshape were aborted in the middle the recorded position would be wrong. On restart it would either fail (as the position wasn't on an appropriate boundary) or would leave a section of the array unreshaped, causing data corruption.
