From cc29591dacdf5f63ada39d1449d52d52890fcdde Mon Sep 17 00:00:00 2001 From: Shyam Prasad N Date: Wed, 3 Jan 2024 12:51:49 +0000 Subject: [PATCH] cifs: update iface_last_update on each query-and-update [ Upstream commit 78e727e58e54efca4c23863fbd9e16e9d2d83f81 ] iface_last_update was an unused field when it was introduced. Later, when we had periodic update of server interface list, this field was used regularly to decide when to update next. However, with the new logic of updating the interfaces, it becomes crucial that this field be updated whenever parse_server_interfaces runs successfully. This change updates this field when either the server does not support query of interfaces; so that we do not query the interfaces repeatedly. It also updates the field when the function reaches the end.
