Make sure to properly invalidate the pagecache before performing direct I/O, so that no stale pages are left around. This matches what the generic direct I/O code does. Also take the i_mutex over the direct write submission to avoid the lifelock vs truncate waiting for i_dio_count to decrease, and to avoid having the pagecache easily repopulated while direct I/O is in progrss. Again matching the generic direct I/O code. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Trond Myklebust <trond.myklebust@primarydata.com>
