Dynamic debugging of kernel
===

I have enabled the `CONFIG_DYNAMIC_DEBUG` flag in kernel config file. when i boot in my system i am able to mount the`/sys/kernel/debug` and there is `dynamic_debug/control` file too.

But when  i issue any command like `echo -n 'module nfsd +p' > <debugfs>/dynamic_debug/control` it does not shows any output in `dmesg` OR `syslogd`.


Thanks
