Subject: Re: [PATCH v5 06/36] cleanup: Basic compatibility with context analysis
Date: Tue, 27 Jan 2026 10:14:23 +0000 [thread overview]
Message-ID: <0c2d9b69-c052-4075-8a4b-023d277b8509@lucifer.local> (raw)
In-Reply-To: <20251219154418.3592607-7-elver@google.com>
+cc Sid for awareness
Hi,
This patch breaks the radix tree and VMA userland tests. The next bots didn't
catch it but it seems now they're building the userland VMA tests
(e.g. https://lore.kernel.all/202601271308.b8d3fcb6-lkp@intel.com/) but maybe
not caught up to the issue this one caused (fails build in tools/testing/vma and
tools/testing/radix-tree).
Anyway it's a really easy fix, just need to stub out __no_context_analysis in
the tools/include copy of compiler_types.h, fix-patch provided below.
To avoid bisection hazard it'd be nice if it could be folded into this series
before this patch, but if we're too late in the cycle for that I can submit a
fix separately.
Thanks, Lorenzo
