We get 2 warnings when building kernel with W=1: drivers/staging/lustre/lustre/obdclass/linux/linux-module.c:413:5: warning: no previous prototype for 'class_procfs_init' [-Wmissing-prototypes] drivers/staging/lustre/lustre/obdclass/linux/linux-module.c:449:5: warning: no previous prototype for 'class_procfs_clean' [-Wmissing-prototypes] In fact, both functions are declared in drivers/staging/lustre/lustre/obdclass/class_obd.c,but should be declared in a header file, thus can be recognized in other file. So this patch moves the declarations into drivers/staging/lustre/lustre/include/obd_class.h.
