many functions (like osc_setattr()) call ptlrpc_request_free() after failed ptlrpc_request_pack() to release the request. this seem to leave the import referenced and then lead to umount getting stuck. |

This would be a good place to fix the strange error handling in __ptlrpc_request_bufs_pack() where we drop a reference on the import. See http://review.whamcloud.com/#/c/16765/. |
