Hello The current crypto_engine support only ahash and ablkcipher request. My first patch which try to add skcipher was Nacked, it will add too many functions and adding other algs(aead, asymetric_key) will make the situation worst. This patchset remove all algs specific stuff and now only process generic crypto_async_request. The requests handler function pointer are now moved out of struct

v5: - Break the btrfs patch out as a separate patch to be processed independently. - Update the commit log of patch 1 to make it less scary. - Add a kzfree backward compatibility macro in patch 2. v4: - Break out the memzero_explicit() change as suggested by Dan Carpenter so that it can be backported to stable. - Drop the "crypto: Remove unnecessary

v4: - Break out the memzero_explicit() change as suggested by Dan Carpenter so that it can be backported to stable. - Drop the "crypto: Remove unnecessary memzero_explicit()" patch for now as there can be a bit more discussion on what is best. It will be introduced as a separate patch later on after this one is merged. This patchset makes a global rename of the kzfree()

This patchset makes a global rename of the kzfree() to kfree_sensitive() to highlight the fact buffer clearing is only needed if the data objects contain sensitive information like encrpytion key. The fact that kzfree() uses memset() to do the clearing isn't totally safe either as compiler may compile out the clearing in their optimizer. Instead, the new kfree_sensitive() uses
