Yes, this is the right solution. Note that this part of the series originally
came from Al Viro, but I added more patches following the same idea.

While working on a follow-up series, I now also noticed that the
FS_IOC_RESVSP compat handler has always been broken for
x32 user space. I don't think anyone cares, but my series in [1]
addresses this as well by handling FS_IOC_RESVSP/
FS_IOC_UNRESVSP/FS_IOC_ZERO_RANGE on x86-64 as
well, in addition to FS_IOC_RESVSP_32 etc.
