Trond Myklebust 0f1d260550 NFS: Don't check lock owner compatibility in writes unless file is locked 
If we're doing buffered writes, and there is no file locking involved,
then we don't have to worry about whether or not the lock owner information
is identical.
By relaxing this check, we ensure that fork()ed child processes can write
to a page without having to first sync dirty data that was written
by the parent to disk.
