Description

Configuring an o2ib NI using lnetctl net add --nid causes a weird, negative memory leak (we free more than allocated?):
[root@s-lmo-gaz38b tests]# lnetctl lnet configure
[root@s-lmo-gaz38b tests]# lnetctl net add --nid 172.18.2.8@o2ib
[root@s-lmo-gaz38b tests]# lustre_rmmod
[root@s-lmo-gaz38b tests]# dmesg | grep leak
[190208.859038] LNetError: 886787:0:(module.c:676:libcfs_exit()) Portals memory leaked: -5 bytes
[root@s-lmo-gaz38b tests]#
