Subject: [PATCH 1/3] docs: sysctl/kernel: Add missing bit to panic_print
Date: Tue, 9 Nov 2021 17:28:46 -0300 [thread overview]
Message-ID: <20211109202848.610874-2-gpiccoli@igalia.com> (raw)
In-Reply-To: <20211109202848.610874-1-gpiccoli@igalia.com>
Commit de6da1e8bcf0 ("panic: add an option to replay all the printk message in buffer")
added a new bit to the sysctl/kernel parameter "panic_print", but the
documentation was added only in kernel-parameters.txt, not in the sysctl guide.
Fix it here by adding bit 5 to sysctl admin-guide documentation.
