[PATCH] Shut up warnings in ipc/shm.c
Fix two warnings in ipc/shm.c ipc/shm.c:122: warning: statement with no effect ipc/shm.c:560: warning: statement with no effect by converting the macros to empty inline functions. For safety, let's do all three. This also has the advantage that typechecking gets performed even without CONFIG_SHMEM enabled.
