[Cluster-devel] [PATCHv2 RESEND v5.10-rc2 11/13] fs: dlm: fix check for multi-homed hosts

[Alexander Aring <aahringo@redhat.com>]

This patch will use the runtime array size dlm_local_count variable
to check the actual size of the dlm_local_addr array. There exists
currently a cleanup bug, because the tcp_listen_for_all() functionality
might check on a dangled pointer.
