We get 3 warnings when building kernel with W=1: drivers/staging/lustre/lustre/obdclass/obd_mount.c:705:5: warning: no previous prototype for 'lustre_check_exclusion' [-Wmissing-prototypes] drivers/staging/lustre/lustre/obdclass/obd_mount.c:1226:5: warning: no previous prototype for 'lustre_register_fs' [-Wmissing-prototypes] drivers/staging/lustre/lustre/obdclass/obd_mount.c:1231:5: warning: no previous prototype for 'lustre_unregister_fs' [-Wmissing-prototypes] In fact, the first function is declared in drivers/staging/lustre/lustre/obdclass/obd_config.c, and the other two functions are declared in drivers/staging/lustre/lustre/obdclass/class_obd.c, but all of these functions 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.
