Subject: NEW GCC EXTENSION for kernel memory management.

Hello Kernel People,

I have developed a new GCC extension called reftrack that could be used for reference counting. Instead of manually adding code for
add()/dec() the reference count, it could be generated by this extension. 

1-minute intro 

If you have a structure S like this

typedef struct S S;
S *p = ... , *q = ...;
p = q;

It gets transformed into 

typedef struct S S;
S *p = ... , *q = ...;
S_addref(q);
S_removeref(p);
p = q;

The extension is available at https://github.com/acbits/reftrack-plugin. I have also attached a prototype kernel implementation with this email.

All suggestions welcome.

Regards

Aravind
