Janpieter Sollie added an attachment on Kernel.org Bugzilla: Created attachment 306999 kernel .config tried both GCC and clang: Clang output: > ld.lld: error: undefined symbol: nfs_to > >>> referenced by localio.c:37 (fs/nfsd/localio.c:37) > >>> vmlinux.o:(init_nfsd) > >>> referenced by localio.c:37 (/usr/src/linux/fs/nfsd/localio.c:37) > >>> vmlinux.o:(nfsd_localio_ops_init) > > ld.lld: error: undefined symbol: nfs_uuid_invalidate_clients > >>> referenced by nfsctl.c:2286 (/usr/src/linux/fs/nfsd/nfsctl.c:2286) > >>> vmlinux.o:(nfsd_net_pre_exit) > > ld.lld: error: undefined symbol: nfs_uuid_is_local > >>> referenced by localio.c:116 (/usr/src/linux/fs/nfsd/localio.c:116) > >>> vmlinux.o:(localio_proc_uuid_is_local) GCC output: ld: fs/nfsd/nfsctl.o: in function `nfsd_net_pre_exit': nfsctl.c:(.text+0x122): undefined reference to `nfs_uuid_invalidate_clients' ld: fs/nfsd/localio.o: in function `localio_proc_uuid_is_local': /usr/src/linux/fs/nfsd/localio.c:116:(.text+0x56): undefined reference to `nfs_uuid_is_local' ld: fs/nfsd/localio.o: in function `nfsd_localio_ops_init': /usr/src/linux/fs/nfsd/localio.c:37:(.text+0x2c9): undefined reference to `nfs_to' Command: make -j64 or make LLVM=1 -j64 the config file for GCC will be attached, let me know if the clang version is desired as well As you might guess, not trimming the unused symbols fixes the issue ...
