Subject: [PATCH 2/2] Documentation/kernel-parameters.txt: Add kernel parameter of squashfs fragments' cache size
Date: Thu, 19 Oct 2017 07:51:00 +0800 [thread overview]
Message-ID: <1508370660-6343-3-git-send-email-wuqixuan@huawei.com> (raw)
In-Reply-To: <1508370660-6343-1-git-send-email-wuqixuan@huawei.com>
Currently, squashfs fragments' cache size is only determined by
config option CONFIG_SQUASHFS_FRAGMENT_CACHE_SIZE. Users have
no way to change the value when they get the binary kernel.
Now make it be configured during booting.
