| Subject: ocfs2: Compute metaecc for superblocks during online resize. |
| |
| From: Joel Becker <joel.becker@oracle.com> |
| |
| 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. |
