From 565674d613d7f45d87284ba9f0be730ce4b335d0 Mon Sep 17 00:00:00 2001 From: Stefan Metzmacher Date: Tue, 21 Jul 2020 09:36:38 -0300 Subject: cifs: merge __{cifs,smb2}_reconnect[_tcon]() into cifs_tree_connect() They were identical execpt to CIFSTCon() vs. SMB2_tcon(). These are also available via ops->tree_connect().
