ocfs2: zero tail of sparse files on truncate
Since we don't zero on extend anymore, truncate needs to be fixed up to zero the part of a file between i_size and and end of it's cluster. Otherwise a subsequent extend could expose bad data. This introduced a new helper, which can be used in ocfs2_write(). Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
