Next: [PATCH] tracing/kprobes: fix probe parsing
From: Arnd Bergmann on 10 Feb 2010 10:20 md ioctls are now handled by the md driver itself, but mdadm may call RAID_VERSION on other devices as well. Mark the command as IGNORE_IOCTL so this fails silently rather than printing an annoying message. Reported-by: "Michael S. Tsirkin" <m.s.tsirkin(a)gmail.com> Cc: "Rafael J.
