[lustre-devel] [PATCH 008/622] lustre: obdecho: turn on async flag only for mode 3

[James Simmons]

From: Rahul Deshmukh <rahul_deshmukh at xyratex.com>

There are couple of problems in obdfilter-survey:
- Type of test brw i.e. "g" was not followed with npages,
- Target netdisk was not set properly and
- Turn ON async flag only for mode 3.

This patch fixes the last problem which is kernel side.
