From: Christoph Hellwig <hch@xxxxxxxxxxxxx> Upstream commit: 5a93a064d27b42e4af1772b0599b53e3241191ac When we call xfs_flush_buftarg (generally from sync or umount) it already is too late to flush the data workqueues, as I/O completion is signalled for them and we are thus already done with the data we would flush here. There are places where flushing them might be useful, but the current sync interface doesn't give us that opportunity.
