From cd5c91fe62519af6af238bbead32f2943a85c7de Mon Sep 17 00:00:00 2001 From: Colin Ian King Date: Tue, 22 Jun 2021 16:16:08 +0100 Subject: crypto: qat - ratelimit invalid ioctl message and print the invalid cmd Currently incorrect QAT ioctls can spam the kernel log with error messages of the form "QAT: Invalid ioctl" if a userspace program uses the wrong ioctl command. Quench the messages by ratelimiting them and also print the invalid command being used as that is useful to know.
