Macro symbol_put() is defined as __symbol_put(__stringify(x))

    ksym_name = "jiffies"
    symbol_put(ksym_name)

will be resolved as

    __symbol_put("ksym_name")

which is clearly wrong. So symbol_put must be replaced with __symbol_put.

When we uninstall hw_breakpoint.ko (rmmod), a kernel bug occurs with the
following error:
