From c0920cd36f17f0729927b33009ca586be50e3d9b Mon Sep 17 00:00:00 2001 From: Mike Christie <michael.christie@oracle.com> Date: Tue, 25 May 2021 13:18:01 -0500 Subject: scsi: iscsi: iscsi_tcp: Set no linger Userspace (open-iscsi based tools at least) sets no linger on the socket to prevent stale data from being sent. However, with the in-kernel cleanup if userspace is not up the sockfd_put will release the socket without having set that sockopt. iscsid sets that opt at socket close time, but it seems ok to set this at setup time in the kernel for all tools.
