This series looks like a fix, but its commit messages seem to be missing some information: - How the issue was discovered, e.g. hit in production, hit during development, syzbot report, manual code inspection, LLM or static analysis tool scan. - Whether the issue was actually triggered, or is only theoretical (e.g. found by code inspection). If it was triggered please include the symptoms, like the stack trace or error messages. - What hardware the change was tested on. For driver fixes please mention the device (and if relevant firmware version) used for testing, or say that the change was not tested on real hardware. Please do not repost the series just to address the above. Instead, reply to this email with the missing information, so that reviewers can take it into account. If the series needs another revision for other reasons, please include the information in the commit messages then.
