Subject: [RFC PATCH v9 02/26] RDMA/rxe: Move rxe_mcast_attach/detach to rxe_mcast.c
Date: Thu, 27 Jan 2022 15:37:31 -0600 [thread overview]
Message-ID: <20220127213755.31697-3-rpearsonhpe@gmail.com> (raw)
In-Reply-To: <20220127213755.31697-1-rpearsonhpe@gmail.com>
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.
Signed-off-by: Bob Pearson <rpearsonhpe@gmail.com>
