From 2bd30b8dc75b823dd7bbef9d7bc68e1fd7ecee5c Mon Sep 17 00:00:00 2001 From: Sang-Heon Jeon Date: Mon, 24 Aug 2026 01:18:14 +0900 Subject: coccinelle: alloc_cast: drop removed allocators - pci_alloc_consistent() and pci_zalloc_consistent() were removed by commit 7968778914e5 ("PCI: Remove the deprecated "pci-dma-compat.h" API") - kmem_alloc() was removed by commit f078d4ea8276 ("xfs: convert kmem_alloc() to kmalloc()") - kmem_zalloc() was removed by commit 10634530f7ba ("xfs: convert kmem_zalloc() to kzalloc()") - kmem_zone_alloc() and kmem_zone_zalloc() were removed by commit bae633a4a283 ("xfs: remove xfs_zone_{alloc,zalloc} helpers") So drop them from the rules. No functional change.

Before starting, read the whole process documentation listed above, as well + as any other document mentioned in the request. Do not rely on isolated + parts found by keyword search. +2. Note the commit ID and Locate a bug as instructed. +3. For any bug found that is not trivial, verify that it looks real by + attempting to create a reproducer to demonstrate it. Lacking it may cause + the report to be ignored, as many unverified bug reports sent to maintainers + happen to be invalid. Stop here if it finally looks wrong. +4. Write a fix for the bug. This part is not optional: except in a few very + rare cases, an AI assistant able to find a bug is able to fix it. Note that + fixes written in the same session as used to find the bug will generally + lead to better and more accurate fixes as the LLM's reasoning context + remains present. +5. Build and verify that the fix works either using the reproducer or by + re-running a complete analysis; drop any fix that doesn't work and try + another one. The fix must not add build warnings and must pass the + checkpatch.pl checks (see submitting-patches.rst). +6. Commit the working fix with a detailed message describing the problem, the + solution and a Fixes tag. Do not add a Signed-off-by tag, and add an + Assisted-by tag, as described above. +7. Identify the maintainers and lists using scripts/get_maintainer.pl. + Documentation/process/security-bugs.rst shows how to do that. +8. Indicate what could not be done. If the fix could not be built or tested, or + if no reproducer could be produced, say so explicitly: maintainers currently + waste too much time analyzing unverified reports and untested fixes. +9. Read Documentation/process/threat-model.rst to determine whether the bug is + a vulnerability or a regular bug, and leave the result to the reporter for + review (the assistant must never send anything itself). Regular bugs are + submitted as described in Documentation/process/submitting-patches.rst, + vulnerabilities as described in Documentation/process/security-bugs.rst. -- cgit v1.3.1
