Subject: [PATCH AUTOSEL 6.1 6/6] riscv: Bump COMMAND_LINE_SIZE value to 1024
Date: Thu, 16 Mar 2023 12:33:07 -0400	[thread overview]
Message-ID: <20230316163309.708796-6-sashal@kernel.org> (raw)
In-Reply-To: <20230316163309.708796-1-sashal@kernel.org>

From: Alexandre Ghiti <alex@ghiti.fr>

[ Upstream commit 61fc1ee8be26bc192d691932b0a67eabee45d12f ]

Increase COMMAND_LINE_SIZE as the current default value is too low
for syzbot kernel command line.

There has been considerable discussion on this patch that has led to a
larger patch set removing COMMAND_LINE_SIZE from the uapi headers on all
ports.  That's not quite done yet, but it's gotten far enough we're
confident this is not a uABI change so this is safe.
