From 758c7f1e9cc9f1d1da480dcde34430ae56888c76 Mon Sep 17 00:00:00 2001 From: Bob Pearson Date: Thu, 27 Jan 2022 15:37:31 -0600 Subject: [PATCH] RDMA/rxe: Move rxe_mcast_attach/detach to rxe_mcast.c Move rxe_mcast_attach and rxe_mcast_detach from rxe_verbs.c to rxe_mcast.c, Make non-static and add declarations to rxe_loc.h. Make the subroutines in rxe_mcast.c referenced by these routines static and remove their declarations from rxe_loc.h.
