Re: [PATCH v2 2/3] cifs: warn about deprecation of /proc/fs/cifs/OplockEnabled interface

Minor clarification - the readme mentions

	/proc/module/cifs/parameters/<param>

i.e. echo "value" > /proc/module/cifs/parameters/<param>

but in my system they are under /sys/module/....  not /proc/module/....
