FWIW, this is just what we need for recoalescing pages when IO fails.
Currently ld_read/write_done is called in default workqueue, which is
not really a good place for IO path code. Trond mentioned that nfsiod
is not an ideal place for it either. So do we need to create a pnfs
private workqueue for this? Any other suggestions?
