Hi all,
this series has two fixes for the XFS compat ioctl handling:
1) always fall back to the native handler if we don't have a compat
handler. This ensures we don't miss adding new ioctls, like we
did for a few recent ones
2) use compat_ptr() properly (from Arnd)
Depending on how important this is we could either queue it up for
5.3, or hand it off to Arnd for his compat ioctl cleanup series
targeted at 5.4.
