Thanks a lot Naresh, this was reported already by Thorsten and me yesterday:

    
https://lore.kernel.org/rust-for-linux/8aa05f08-ef6e-4dfe-9453-beaab7b3c...@leemhuis.info/

A patch from Danilo is in flight to fix it:

    
https://lore.kernel.org/rust-for-linux/20250818180923.192042-1-d...@kernel.org/

If you could test it, that would be great. I assume Danilo will apply
the patch on top of alloc-next, since the issue is just inside that
branch that goes into linux-next.

Thanks!

Cheers,
Miguel
