kzfree(9) like kfree but zero memory

SYNOPSIS

void kzfree(const void * p);

ARGUMENTS

p

object to free memory of

DESCRIPTION

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.
