fs/lockd/Makefile:
obj-$(CONFIG_LOCKD) += lockd.o
lockd-objs-y := clntlock.o clntproc.o clntxdr.o host.o svc.o svclock.o \
svcshare.o svcproc.o svcsubs.o mon.o xdr.o grace.o
your patch adds a module_init to svcsubs.c.
However, there is already one in svc.c, pulled into the same module.
in your test build, is CONFIG_LOCKD defined as "m" or "y" ? You should
always test both.
One solution here is to create a "local" init function in svcsubs.c and
expose it to svc.c, so the latter can call it from its module init
function.
Thanks,
Mathieu
