[PATCH] RDMA/rxe: Remove useless pkt parameters

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The pkt parameters in prepare_ack_packet(), send_ack() and
send_atomic_ack() have become useless by the following commits.
So remove them directly.

Fixes: bf139b58af09 ("RDMA/rxe: Remove unused pkt->offset")
Fixes: 3896bde92d03 ("RDMA/rxe: Fix extra copy in prepare_ack_packet")
