The filesystems or helpers they use normally did not even check the -Exyz error they were getting except for -EOPNOTSUPPORTED. They typically use the uptodate bits on the bio or buffer head. A greater discussion on what the FS's needed and what actions they should take would be good though, I agree. They never responded in the past so I thought the MD and DM were the only interested users for now. I will post to lkml or fs-devel next time. Sorry about that.
