Subject: [hardknott 12/14] zram: add support for mem_limit
Date: Mon,  3 May 2021 12:12:05 -0700	[thread overview]
Message-ID: <ef6adcba6f45ff84b5150c372c50f270edc3cc76.1620069042.git.akuster808@gmail.com> (raw)
In-Reply-To: <cover.1620069041.git.akuster808@gmail.com>

From: Sinan Kaya <okaya@kernel.org>

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.
