XFS ioctls not being included

[robbat2]

fs/xfs/libxfs/xfs_fs.h contains all of the XFS ioctls, which don't seem to get included in in the building of the list.

I'm most interested in being able to run XFS_IOC_GOINGDOWN.

Just to make sure, you are generating a new ioctl_list.c and not using the included one, right? Try deleting the file and running make.

Yes, I did regenerate it.

25 entries missing:

From my point of view, kernel maintainer of xfs should export their headers to the userspace (by placing them in include/uapi).

As workaround, you will have to update ioctls_list.c manually.
