From 996e2523cc347cc98237d2da3454aedc779fdcba Mon Sep 17 00:00:00 2001 From: Herbert Xu Date: Sun, 21 May 2006 11:57:20 +1000 Subject: [CRYPTO] api: Allow replacement when registering new algorithms We already allow asynchronous removal of existing algorithm modules. By allowing the replacement of existing algorithms, we can replace algorithms without having to wait for for all existing users to complete.
