orangefs: don't mess with I_DIRTY_TIMES in orangefs_flush
Christoph Hellwig noticed that we were doing some unnecessary work in orangefs_flush: orangefs_flush just writes out data on every close(2) call. There is no need to change anything about the dirty state, especially as orangefs doesn't treat I_DIRTY_TIMES special in any way. The code seems to come from partially open coding vfs_fsync. He sent in a patch with the above commit message and also a patch that was a reversion of another Orangefs patch I had sent upstream a while ago. I had to fix his reversion patch so that it would compile which caused his "don't mess with I_DIRTY_TIMES" patch to fail to apply. So here I have just remade his patch and applied it after the fixed reversion patch. Signed-off-by: Mike Marshall <hubcap@omnibond.com>
