From d4f9df9159c5ac93b97c36b0f98ffbd318866e38 Mon Sep 17 00:00:00 2001 From: Jeff Layton Date: Thu, 13 Dec 2012 08:58:54 -0500 Subject: cifs-utils: struct cifs_sid definition to new cifsidmap.h header People who want to build a plugin for the idmapping routines will need a header to describe the data types that they need. Add a cifsidmap.h file and move the struct cifs_sid definition into it, along with the constants needed to describe it.
