For a Linux server with NUMA, there are possibly multiple (de)compressors
which are either local or remote to some NUMA node. Some drivers will
automatically use the (de)compressor near the CPU calling acomp_alloc().
However, it is not necessarily correct because users who send acomp_req
could be from different NUMA node with the CPU which allocates acomp.

Just like kernel has kmalloc() and kmalloc_node(), here crypto can have
same support.

Hi Barry,

Seems sensible to me.  A few trivial comments inline.

Thanks,

Jonathan

Given slightly relaxed view on 80 chars now in place, I'd put that on one line.

Also kernel-doc needs to be complete so though it's tedious you should document
the other parameters.

Stray change. Shouldn't be in this patch.

You mean here the doc for other parameters should be copied from crypto_alloc_acomp()? 
If so, it is ok to me :-)
