Subject: [PATCH 7/8] zram: remove max_num_devices limitation
Date: Thu, 26 Feb 2015 23:10:42 +0900	[thread overview]
Message-ID: <1424959843-20409-8-git-send-email-sergey.senozhatsky@gmail.com> (raw)
In-Reply-To: <1424959843-20409-1-git-send-email-sergey.senozhatsky@gmail.com>

Limiting the number of zram devices to 32 (default max_num_devices value)
is confusing, let's drop it. A user with 2TB or 4TB of RAM, for example,
can request as many devices as he can handle.
