[Openib-windows] [PATCH] MT23108: Fix large buffer memoryregistration

[Guy Corem]

I'm worried about the following line:
new_iobuf->va = va;

In register_segment().

The seg_va, rdc, and seg_size are only used to pin the pages.  The
input va and size are used in the iobuf structure, as well as being
used to calculate the expected number of pages in the MR.  We don't
touch the original va and size, so everything should be fine.
