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

From: Greg KH
Date: Mon May 10 2010 - 19:00:09 EST


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.
