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.

Always try the native ioctl if we don't have a compat handler. This
removes a lot of boilerplate code as 'modern' ioctls should generally
be compat clean, and fixes the missing entries for the recently added
FS_IOC_GETFSLABEL/FS_IOC_SETFSLABEL ioctls.

For 31-bit s390 user space, we have to pass pointer arguments through
compat_ptr() in the compat_ioctl handler.

So, what is the plan? Do you think they are worth including for 5.3,
or do you want to pass them off to Arnd for his series that is targeted
at 5.4?

I'll combine these two with the reflink/dedupe locking fixes and push
