Description of problem: When gfs_grow is running, the locking traffic is significant enough to make dlm_send look like it's spinning and the system becomes less responsive. This load seems excessive.

The locking traffic is what was slowing down gfs_grow in bug #485451, and the solution in bug #485451 is to reduce the locking traffic by combining writes. Therefore, I'm closing this bug as a duplicate. *** This bug has been marked as a duplicate of bug 485451 ***
