Re: [Cluster-devel] [PATCH v7 16/19] iomap: Add done_before argument to iomap_dio_rw

[Christoph Hellwig]

What about just passing done_before as an argument to
iomap_dio_complete? gfs2 would have to switch to __iomap_dio_rw +
iomap_dio_complete instead of iomap_dio_rw for that, and it obviously
won't work for async completions, but you force sync in this case
anyway, right?
