Subject: Per-cpu tfm allocation/free functions
Date: Thu, 01 Dec 2011 11:01:00 -0600 [thread overview]
Message-ID: <4ED7B2CC.3090209@linux.vnet.ibm.com> (raw)
linux-crypto,
I am currently working on the zcache RAM compression driver (in the staging
tree) and have a question.
I am looking to use the crypto compression API instead of the hardcoded LZO
calls that are in there right now, but I need to allocate a tfm per cpu per
compression algorithm being used.
I've already written the code but it looks very similar to what is already in
ipcomp_alloc/free_tfms() in net/xfrm/xfrm_ipcomp.c.
Has there ever been any talk about implementing functions like that inside
the cryptographic API in order to prevent duplicate per-cpu code by the users?
Would there be any interest/objections regarding a patch that did implement them?
