From: Jian Yu Date: Mon, 3 Jun 2013 13:40:59 +0000 (+0800) Subject: staging/lustre/tests: check nr_local in ofd_preprw() X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=09b0170e677708547df3f77ad8dccc29c88e2e81;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git staging/lustre/tests: check nr_local in ofd_preprw() 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.
