What is the advantage over just using a consistent prefix? Using "blk_crypto_fallback_*" for all these variables results in some pretty long names, e.g. "blk_crypto_fallback_crypt_ctx_cache" and "blk_crypto_fallback_num_prealloc_crypt_ctxs". This proposal gives the best of both worlds; the names are properly "namespaced" but there is also a shortcut to refer to them (struct blk_crypto_fallback *fallback = &blk_crypto_fallback). If this is going to be controversial I can just drop this patch, but I was hoping there would be a way to make things more consistent. - Eric -- dm-devel mailing list dm-devel@redhat.com https://listman.redhat.com/mailman/listinfo/dm-devel
