Subject: [PATCH 2/3] panic: refine the document for 'panic_print'
Date: Fri, 15 Aug 2025 15:14:27 +0800 [thread overview]
Message-ID: <20250815071428.98041-3-feng.tang@linux.alibaba.com> (raw)
In-Reply-To: <20250815071428.98041-1-feng.tang@linux.alibaba.com>
User reported current document about SYS_INFO_PANIC_CONSOLE_REPLAY
is confusing, that people could expect all user space console messages
to be replayed.
Specify that only 'kernel' messages will be replayed to solve the confusion.
Reported-by: Askar Safin <safinaskar@zohomail.com>
