Subject: RDS: Remove stale function rds_send_get_message()
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=7d885d0fc69abe22382fae5dddd84684333ab29b;p=deliverable%2Flinux.git

RDS: Remove stale function rds_send_get_message()

The only caller of rds_send_get_message() was
rds_iw_send_cq_comp_handler() which was removed as part of
commit dcdede0406d3 ("RDS: Drop stale iWARP RDMA transport"),
so remove rds_send_get_message() for the same reason.
