From 29e20f9c65fae245d6fd4fce31cc5d01cde3d93f Mon Sep 17 00:00:00 2001 From: Pavel Shilovsky Date: Fri, 13 Jul 2012 13:58:14 +0400 Subject: CIFS: Make CAP_* checks protocol independent Since both CIFS and SMB2 use ses->capabilities (server->capabilities) field but flags are different we should make such checks protocol independent.
