GFS2: No need to invalidate pages for a dio read We recently fixed the writeback of pages prior to performing direct i/o, however the initial fix was perhaps a bit heavy handed. There is no need to invalidate pages if the direct i/o is only a read, since they will be identical to what has been flushed to disk anyway. Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>
