Yeah, the notifier code remains untouched as we still do not allow dynamic
memory operations _while_ our module is loaded. The patch allows the
driver to
cope with DMEM operations that happened before the module was loaded, which
might result in a non-contiguous memory layout. When the driver registers
its global memory region in the system, the memory layout must be
considered.
We chose the term toleration instead of support to illustrate this.
I see. So things just silently broke in some cases when the driver was
loaded after operations you didn't tolerate?
Anyway, thanks for the explanation.
Well, things did not break silently. The registration of the MR failed with
an error code which was reported to userspace.
Will you push the patch for .31 or .32?
Thanks,
Alex
