From 281e2e7d06c42ce8dfd423fa2ae5616af0e0323f Mon Sep 17 00:00:00 2001 From: Jeff Layton Date: Sun, 26 May 2013 07:00:56 -0400 Subject: [PATCH] cifs: remove the cifs_ses->flags field This field is completely unused: CIFS_SES_W9X is completely unused. CIFS_SES_LANMAN and CIFS_SES_OS2 are set but never checked. CIFS_SES_NT4 is checked, but never set.
