The removed code in err.c
- /*
- * su-sis may be in assigning/removing state. signal csi
- * assign/remove done so that su-si assignment/removal algo can proceed.
- */
- avnd_comp_cmplete_all_assignment(cb, failed_comp);
-
and
/* delete curr info of the failed comp */
- rc = avnd_comp_curr_info_del(cb, failed_comp);
- if (NCSCC_RC_SUCCESS != rc)
- goto done;
-
is added in avnd_comp_clc_terming_cleansucc_hdler() and
avnd_comp_clc_terming_termsucc_hdler().
Don't we require the code in avnd_comp_clc_terming_cleanfail_hdler()
when cleanup of component fails?
Thanks
