cifs: show features compiled in as part of DebugData
Fixed the nit pointed out by Jeff. From: Suresh Jayaraman <sjayaraman@suse.de> Subject: [PATCH 1/2] cifs: show features compiled in as part of DebugData This patch adds the features that are compiled in to the CIFS debugging data as shown below: $cat /proc/fs/cifs/DebugData Display Internal CIFS Data Structures for Debugging --------------------------------------------------- CIFS Version 1.64 Features: dfs fscache posix spnego xattr Active VFS Requests: 0 ... This patch provides a definitive way to tell what features are currently enabled in the running kernel. This could also help debugging.
