[28/98] ocfs2: Compute metaecc for superblocks during online resize.

[Greg KH]

2.6.32-stable review patch.  If anyone has any objections, please let us know.

------------------

From: Joel Becker <joel.becker@xxxxxxxxxx>

commit a42ab8e1a37257da37e0f018e707bf365ac24531 upstream.

Online resize writes out the new superblock and its backups directly.
The metaecc data wasn't being recomputed.  Let's do that directly.
