----- Original Message -----
| In some places, it's trying to reset the mapping error after calling
| filemap_fdatawait. That's no longer required. Also, turn several
| filemap_fdatawrite+filemap_fdatawait calls into filemap_write_and_wait.
| That will at least return writeback errors that occur during the write
| phase.

This part doesn't look right at all. There's a big difference in gfs2 between
mapping and metamapping. We need to wait for metamapping regardless.
