Akmods fails on Fedora 32. Can't find ioctl32.h

I’m trying to install the Nvidia/CUDA drivers on my laptop (Fedora 32) with

5.10.7-100.fc32.x86_64 #1 SMP Tue Jan 12 20:25:28 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux
00:02.0 VGA compatible controller: Intel Corporation 3rd Gen Core processor Graphics Controller (rev 09)
01:00.0 VGA compatible controller: NVIDIA Corporation GK107M [GeForce GT 650M] (rev a1)

with the instructions at RPM Fusion but when akmods fails because it can’t find the ioctl32.h, e.g.,

2021/01/16 22:08:09 akmodsbuild: /tmp/akmodsbuild.anCurKbI/BUILD/nvidia-kmod-440.82/_kmod_build_5.10.7-100.fc32.x86_64/common/inc/nv-linux.h:160:10: fatal error: linux/ioctl32.h: No such file or directory
2021/01/16 22:08:09 akmodsbuild: 160 | #include <linux/ioctl32.h>          /* register_ioctl32_conversion()    */
2021/01/16 22:08:09 akmodsbuild: |          ^~~~~~~~~~~~~~~~~

But I can’t find which package should contain that file.

Any tips?

Thanks!

Sometime in the last twelve hours, the 460 version of the drivers became available and the drivers install without a hitch.

Wild. Timing is everything.
