Hi All,
I have just started to contribute to linux kernel. I was thinking of
giving a patch where a variable is made null after free if not already
done.
Some thing like this:
Original code:
kfree(x);
...........some other code...........
I will change this code to:
New code:
kfree(x);
++ x = NULL;
...........some other code...........
Will this kind of code change be accepted by linux kernel?
Also, isn't doing this a better practice - that is, assigning NULL to
variable after freeing it? What is the best practice? What do people
think about it?
Any feedback / replies will be greatly appreciated.
Regards,
JB
