      NFSv4.1: Clean ups and bugfixes for the pNFS read/writeback/commit code · 8dd37758
      Trond Myklebust 提交于
      Move more pnfs-isms out of the generic commit code.
      
      Bugfixes:
      
      - filelayout_scan_commit_lists doesn't need to get/put the lseg.
        In fact since it is run under the inode->i_lock, the lseg_put()
        can deadlock.
      
      - Ensure that we distinguish between what needs to be done for
        commit-to-data server and what needs to be done for commit-to-MDS
        using the new flag PG_COMMIT_TO_DS. Otherwise we may end up calling
        put_lseg() on a bucket for a struct nfs_page that got written
        through the MDS.
      
      - Fix a case where we were using list_del() on an nfs_page->wb_list
        instead of list_del_init().
      
      - filelayout_initiate_commit needs to call filelayout_commit_release
        on error instead of the mds_ops->rpc_release(). Otherwise it won't
        clear the commit lock.
      
      Cleanups:
      
      - Let the files layout manage the commit lists for the pNFS case.
        Don't expose stuff like pnfs_choose_commit_list, and the fact
        that the commit buckets hold references to the layout segment
        in common code.
      
      - Cast out the put_lseg() calls for the struct nfs_read/write_data->lseg
        into the pNFS layer from whence they came.
      
      - Let the pNFS layer manage the NFS_INO_PNFS_COMMIT bit.

      pnfs-obj: Must return layout on IO error · fe0fe835
      Boaz Harrosh 提交于
      As mandated by the standard. In case of an IO error, a pNFS
      objects layout driver must return it's layout. This is because
      all device errors are reported to the server as part of the
      layout return buffer.
      
      This is implemented the same way PNFS_LAYOUTRET_ON_SETATTR
      is done, through a bit flag on the pnfs_layoutdriver_type->flags
      member. The flag is set by the layout driver that wants a
      layout_return preformed at pnfs_ld_{write,read}_done in case
      of an error.
      (Though I have not defined a wrapper like pnfs_ld_layoutret_on_setattr
       because this code is never called outside of pnfs.c and pnfs IO
       paths)
      
      Without this patch 3.[0-2] Kernels leak memory and have an annoying
      WARN_ON after every IO error utilizing the pnfs-obj driver.
      
      [This patch is for 3.2 Kernel. 3.1/0 Kernels need a different patch]
