/*
Since commit 07d106d0a33d ("vfs: fix up ENOIOCTLCMD error handling"), we don't warn about unhandled compat-ioctl command code any more, but just return the same error that a native file descriptor returns when there is no handler. This means the IGNORE_IOCTL() annotations are completely useless and can all be removed. TIOCSTART/TIOCSTOP and KDGHWCLK/KDSHWCLK fall into the same category, but for some reason were listed as COMPATIBLE_IOCTL().
