Hi,
With command vi in your linux edit this file in SDK directory: ./package/kernel/linux/modules/fs.mk
Find these lines in the file:
define KernelPackage/fs-nfs-common
SUBMENU:=$(FS_MENU)
TITLE:=Common NFS filesystem modules
KCONFIG:= \
CONFIG_LOCKD \
CONFIG_SUNRPC
FILES:= \
$(LINUX_DIR)/fs/lockd/lockd.ko \
$(LINUX_DIR)/net/sunrpc/sunrpc.ko \
AUTOLOAD:=$(call AutoLoad,30,sunrpc lockd)
endef
$(eval $(call KernelPackage,fs-nfs-common))
And add this line next to: other "$(LINUX_DIR)...." lines
$(LINUX_DIR)/fs/nfs_common/grace.ko
Save it and try compiling again.
EB.
