From 2ba0d8947efd49d44babe7a2e72637c630fcfc42 Mon Sep 17 00:00:00 2001 From: Pali Rohár Date: Thu, 12 Sep 2024 14:05:46 +0200 Subject: cifs: Recognize SFU socket type MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit SFU since its (first) version 3.0 supports AF_LOCAL sockets and stores them on filesytem as system file with one zero byte. Add support for detecting this SFU socket type into cifs_sfu_type() function. With this change cifs_sfu_type() would correctly detect all special file types created by SFU: fifo, socket, symlink, block and char.
