The XFS workqueue can't just go away, as for writes that require
completion time processing (unwritten extent conversion, i_size logging,
zoned block mapping), we want to serialize the processing on a per-inode
basis as otherwise the different helpers would just content on the xfs
inode lock and burn cycles.

We want to get rid of it for read completions, and a patch for that is
in the lazy bounce series I posted a few days ago.
