[Ocfs2-devel] [PATCH V2] ocfs2/dlm: fix a variable overflow problem in dlmdomain.c

[piaojun <piaojun@huawei.com>]

In dlm_send_join_cancels(), node is defined with type unsigned int, but
initialized with -1, this will lead variable overflow. Although this
won't cause any runtime problem, the code looks a little uncoordinated.
