Subject: [PATCH] IPVS: change type of netns_ipvs->sysctl_sync_qlen_max
Date: Wed, 20 Feb 2013 07:53:37 +0800 [thread overview]
Message-ID: <51241081.20006@gmail.com> (raw)
From: Zhang Yanfei <zhangyanfei@cn.fujitsu.com>
This member of struct netns_ipvs is calculated from nr_free_buffer_pages
so change its type to unsigned long in case of overflow. Also, type of
its related proc var sync_qlen_max and the return type of function
sysctl_sync_qlen_max() should be changed to unsigned long, too.
Besides, the type of ipvs_master_sync_state->sync_queue_len should be
changed to unsigned long accordingly.
