3.16.65-rc1 review patch. If anyone has any objections, please let me know. ------------------ From: Ben Hutchings <ben@xxxxxxxxxxxxxxx> Revert commit 36a0db05310fbee38b59fed7e1306c1a095f8c8f, a minimal backport of commit cabfb3680f78981d26c078a26e5c748531257ebb upstream. We need a complete backport to avoid a regression for SMB3 authenticated mounts.
