Re: Some memory reallocation in kernel mode

[Ketan Mehta <ketan.mehta@xxxxxxxxx>]

hi,
	what u suggest is what is done by realloc.
	that is what my understanding is . since i don't have something like
realloc in kernel mode, i have to give some max chunk , copy data , then
what is there , accordiing to that create new chunk and copy to that and
free initial one... but it takes time. 
	So i want to know , how i can recover some unused memory chunk
allocated by kmalloc.
	whether it can be done or not.
	bye
