This is wrong.  It will be taken care of by
_pnfs_clear_lseg_from_pages called by pnfs_try_to_write_data.

A partial write, e.g. one that uses nfs_write_partial_ops, does not set nfs_write_data->pages, so _pnfs_clear_lseg_from_pages does not take care of
clearing the req->wb_lseg.


Hmmm, you are right.

Perhaps it would be cleaner to add this case to _pnfs_clear_lseg_from_pages.


I'll look into this, but for now your patch does the correct thing.

I can resend with it moved to _pnfs_clear_lseg_from_pages.

              wdata->pdata.lseg = NULL;
              put_lseg(lseg);
      }
