From 7bc13b5b60e9412a7ddef300ce2c661eecd1fd5d Mon Sep 17 00:00:00 2001 From: Barry Song Date: Sun, 5 Jul 2020 21:18:58 +1200 Subject: crypto: api - permit users to specify numa node of acomp hardware 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.
