Is this the first patch that add the abbreviation "UMR" to a header
file in include/rdma ? If so, I think it's a good idea not only to
mention the abbreviation but also what UMR stands for.
Bart.
You are correct,
I prefer to remove this abbreviation UMR as it is not tightly related to
signature.
The the max_reg_descriptors parameter is the equivalent to
max_page_list_len of ib_alloc_fast_reg_mr().
The difference is that this memory region can also register indirect
memory descriptors {key, addr, len} rather than u64 physical addresses.
For example signature enabled memory region may register 2 descriptors:
data and protection.
I'll modify the explanation here in v3.
Sagi.
