Ocfs2: Fix a regression bug from mainline commit(6b933c8e6f1a2f3118082c455eef25f9b1ac7b45).
The patch is to fix the regression bug brought from commit 6b933c8...( 'ocfs2:
Avoid direct write if we fall back to buffered I/O'):
http://oss.oracle.com/bugzilla/show_bug.cgi?id=1285
The commit 6b933c8e6f1a2f3118082c455eef25f9b1ac7b45 changed __generic_file_aio_write
to generic_file_buffered_write, which didn't call filemap_{write,wait}_range to flush
the pagecaches when we were falling O_DIRECT writes back to buffered ones. it did hurt
the O_DIRECT semantics somehow in extented odirect writes.
This patch tries to guarantee O_DIRECT writes of 'fall back to buffered' to be correctly
flushed.
