Subject: [PATCH 1/2] zsmalloc: remove synchronize_rcu from zs_compact()
Date: Mon, 23 Mar 2015 22:26:38 +0900 [thread overview]
Message-ID: <1427117199-2763-2-git-send-email-sergey.senozhatsky@gmail.com> (raw)
In-Reply-To: <1427117199-2763-1-git-send-email-sergey.senozhatsky@gmail.com>
Do not synchronize rcu in zs_compact(). Neither zsmalloc not
zram use rcu.
