Subject: [PATCH] CIFS: Don't let read only caching for mandatory byte-range
 locked files

If we have mandatory byte-range locks on a file we can't cache reads
because pagereading may have conflicts with these locks on the server.
That's why we should allow level2 oplocks for files without mandatory
locks only.
