The patch below does not apply to the 5.10-stable tree. If someone wants it applied there, or to any other stable or longterm tree, then please email the backport, including the original git commit id to stable@vger.kernel.org.

Oh? I just applied the patch on top of:

commit 272aedd4a305 ("Linux 5.10.87")

without any issues. Not sure what failed for you.

It fails to build :(

I think the issue is probably that capable_wrt_inode_uidgid in kernels of that era didn't take a userns arg. I had to do a similar fixup for the RHEL8 backport.
