New patches are in inspection:
[2.x] http://review.whamcloud.com/#change,432
[1.8] http://review.whamcloud.com/#change,410

[James A Simmons]

For the 2.X patch do you still need the 1.8 patch. The latest on review suggest you don't need a special patch anymore for 1.8 clients.

[nasf (Inactive)]

To make lustre-1.8.6 can work together with lustre-2.x, you can choose either "http://review.whamcloud.com/#change,410" for lustre-1.8.6, or "http://review.whamcloud.com/#change,432" for lustre-2.x, or both of them.

If you only choose "http://review.whamcloud.com/#change,432" for lustre-2.x, you maybe meet the issues of bug 20581, although it is rare case.
