gfs2: jdata writepage fix
[ Upstream commit cbb60951ce18c9b6e91d2eb97deb41d8ff616622 ]
The ->writepage() and ->writepages() operations are supposed to write
entire pages. However, on filesystems with a block size smaller than
PAGE_SIZE, __gfs2_jdata_writepage() only adds the first block to the
current transaction instead of adding the entire page. Fix that.
Fixes: 18ec7d5c3f43 ("[GFS2] Make journaled data files identical to normal files on disk")
