Are all the driver updates the same? It looks like it.
I'd suggest shortening this patch series, have the core provide the
wrapper immediately:
struct ib_mr *ib_alloc_mr(struct ib_pd *pd,
{
...
if (pd->device->alloc_mr) {
mr = pd->device->alloc_mr(pd, mr_type, max_entries, flags);
} else {
if (mr_type != IB_MR_TYPE_FAST_REG || flags ||
!ib_dev->alloc_fast_reg_mr)
return ERR_PTR(-ENOSYS);
mr = pd->device->alloc_fast_reg_mr(..);
}
}
Then go through the series to remove ib_alloc_fast_reg_mr
Then go through one series to migrate the drivers from
alloc_fast_reg_mr to alloc_mr
Then entirely drop alloc_fast_reg_mr from the driver API.
That should be shorter and easier to read the driver diffs, which is
the major change here.
Yea, it would be better...
Thanks.
