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.
