Subject: [meta-oe][PATCH] zram: add support for mem_limit
Date: Fri, 23 Apr 2021 20:03:25 +0000 [thread overview]
Message-ID: <20210423200325.3204-1-okaya@kernel.org> (raw)
Some targets might be interested in limiting how big
zram can grow. If the variable is set in /etc/default/zram file,
configure it in mem_limit sysfs attribute.
