I think roughly adding something like this to general networking entry? F: io_uring/zcrx.* K: \bnet(mem_ref|_iov)\b I had suggested this before but never had time to suggest the actual changes, and in the back of my mind was a bit weary of spamming the maintainers, but it seems this is not as much a concern as the patches not getting to netdev. --=20 Thanks, Mina
