From aabf4851d1605523be8f2518e6a549f3f080e198 Mon Sep 17 00:00:00 2001 From: Shyam Prasad N Date: Mon, 30 Oct 2023 11:00:11 +0000 Subject: [PATCH] cifs: force interface update before a fresh session setup commit d9a6d78096056a3cb5c5f07a730ab92f2f9ac4e6 upstream. During a session reconnect, it is possible that the server moved to another physical server (happens in case of Azure files). So at this time, force a query of server interfaces again (in case of multichannel session), such that the secondary channels connect to the right IP addresses (possibly updated now).
