From: Ross Lagerwall <ross.lagerwall@xxxxxxxxxx> [ Upstream commit d8f6382a7d026989029e2e50c515df954488459b ] This reverts commit bbc0f8bd88abefb0f27998f40a073634a3a2db89. It added a warning whose intent was to check whether the rport was still linked into the peer list. It doesn't work as intended and gives false positive warnings for two reasons: 1) If the rport is never linked into the peer list it will not be considered empty since the list_head is never initialized. 2) If the rport is deleted from the peer list using list_del_rcu(), then the list_head is in an undefined state and it is not considered empty.
