+Subject: [Cryptodev-linux-devel] [PATCH v2] Replace INIT_COMPLETION with
+	reinit_completion.
+
+In the 3.13-rc1 Linux kernel, the INIT_COMPLETION macro has been replaced
+with an inline function, reinit_completion [1][2]. We are currently
+using the 3.13-rc3 Linux kernel, which leads to the following error:
+
+cryptlib.c:279:2: error: implicit declaration of function 'INIT_COMPLETION' [-Werror=implicit-function-declaration]
+  INIT_COMPLETION(cdata->async.result->completion);
