      pNFS: Fix missing layoutreturn calls · 13c13a6a
      Trond Myklebust 提交于
      The layoutreturn code currently relies on pnfs_put_lseg() to initiate the
      RPC call when conditions are right. A problem arises when we want to
      free the layout segment from inside an inode->i_lock section (e.g. in
      pnfs_clear_request_commit()), since we cannot sleep.
      
      The workaround is to move the actual call to pnfs_send_layoutreturn()
      to pnfs_put_layout_hdr(), which doesn't have this restriction.

      NFSv4.1/pnfs: Retry through MDS when getting bad length of data · f8417b48
      Kinglong Mee 提交于
      If non rpc-based layout driver return bad length of data, nfs retries
      by calling rpc_restart_call_prepare() that cause an NULL reference panic.
      
      This patch lets nfs retry through MDS for non rpc-based layout driver
      return bad length of data.
