Description

From the documentation it is not clear whether wild-card are suppose work in building tbf jobid rules. My test show it doesn't work.

For example

lctl set_param mds.MDS.mdt.nrs_tbf_rule="start rule1 { *.pbssrv1 } 100"
lctl set_param mds.MDS.mdt.nrs_tbf_rule="start rule2 { *.pbssrv2 } 500"
