The count of the times that this has happened is available via

What kernel provides this? I have system running everything from 2.6.15 
to 2.6.20-get14, and there is no such file in any of them. There is a 
per-device errors file one level down, but that presumably wouldn't be 
in the superblock.

Do I have to go from 0.90 to v1 or later superblocks to get this, and if 
so is that a safe thing to do?
