Enable additional CIFS debugging routines

configname: CONFIG_CIFS_DEBUG2

Linux Kernel Configuration
└─>File systems

└─>Enable additional CIFS debugging routines
In linux kernel since version 2.6.20 (release Date: 2007-02-04)
Enabling this option adds a few more debugging routines
to the cifs code which slightly increases the size of
the cifs module and can cause additional logging of debug
messages in some error paths, slowing performance. This
option can be turned off unless you are debugging
cifs problems. If unsure, say N.
