We did not notice it in the kernel until now because `-Zfixed-x18` has been a target modifier only since 1.88.0 (and it is the only one we use so far). The issue has been reported upstream [1] and a fix has been submitted [2], including a test similar to the kernel case. [ This is now fixed upstream (thanks Guillaume for the quick review), so it will be fixed in Rust 1.90.0 (expected 2025-09-18). - Miguel ] Meanwhile, conditionally pass `-Cunsafe-allow-abi-mismatch=fixed-x18` to workaround the issue on our side.

So __GFP_DIRECT_RECLAIM should be cleared. So, /* Preemption is disabled in ___slab_alloc() */ gfp_flags &= ~(__GFP_DIRECT_RECLAIM); should work? > Of course there are other problems. > > So it is best to limit gtp flags. -- Cheers, Harry / Hyeonggon
