Are you sure all of these are correct? The kernel/user api for lustre
is a complex beast, and just casting away the pointer types isn't
usually the proper thing to do in order to resolve the issues here.

I'm not 100% sure, but the pointers that I added the annotation to end
up being used as user memory. (eg. passed to copy_to_user, etc.)
Sometimes these pointers are passed to functions that already have
__user annotation in their signatures (eg. ll_getname, copy_and_ioctl,
ll_fid2path, etc.).
