So far so good. But one thing I noticed, is that its very chatty to dmesg. eg alloc_nhgrp: new mpath group: num_nhops: 2 compile_nhgrp: O: 2/2 compile_nhgrp: OO[0]: 1/1 curr=1 slot_idx=0 compile_nhgrp: OO[1]: 0/0 curr=1 slot_idx=1 alloc_nhgrp: new mpath group: num_nhops: 2 compile_nhgrp: O: 2/2 compile_nhgrp: OO[0]: 1/1 curr=1 slot_idx=0 compile_nhgrp: OO[1]: 0/0 curr=1 slot_idx=1 alloc_nhgrp: new mpath group: num_nhops: 2 compile_nhgrp: O: 2/2 compile_nhgrp: OO[0]: 1/1 curr=1 slot_idx=0 compile_nhgrp: OO[1]: 0/0 curr=1 slot_idx=1 are these debugging messages that forgot to be turned off ? What do they mean ? Thanks for this work! 13.0-STABLE #11 stable/13-cc1352c1f-dirty ---Mike
