kzfree9
Like kfree but zero memory
Usage
void kzfree(const void * p);
Arguments
p
object to free memory of
Overview
The memory of the object p points to is zeroed before freed. If p is NULL, kzfree does nothing.
Note
this function zeroes the whole allocated buffer which can be a good deal bigger than the requested buffer size passed to kmalloc. So be careful when using this function in performance sensitive code.
