kernel memory allocation

From: João Eduardo Luís <hidden>

Hi.
From [1] I'm lead to believe the only difference between the regular kmalloc() arguments and those of kmalloc_node() is the one specifying which node you want to allocate the memory on.
Aside from the third argument, which seems to be related with NUMA (with which I never worked on kernel-context), I would suggest you to read [2].

If on the other hand you only want to allocate memory locally, maybe you should use kmalloc() or one of its variants [3]. 


Cheers.

Hello all,

I just want to allocate memory for a struct instantiation. Would anyone guide me what arguments I should pass to "kmalloc_node"?
