From: Jian Yu <jian.yu@xxxxxxxxx> This patch checks the number of bulk I/O RPC pages with PTLRPC_MAX_BRW_PAGES in ofd_preprw() to avoid LASSERT(iobuf->dr_npages < iobuf->dr_max_pages) occurring while larger I/O size is specified. The patch also fixes echo_client_prep_commit() to reuse the env context so as to avoid LASSERT(info->fti_exp == NULL) occurring while the bulk I/O size is larger than PTLRPC_MAX_BRW_SIZE. The patch also improves obdfilter-survey to handle the case while interoprating with old server.
