Subject: [DLM] Clear othercon pointers when a connection is closed
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=25720c2d73058f4f929f16093f60817ed52a285c;p=GitHub%2Fmt8127%2Fandroid_kernel_alcatel_ttab.git

[DLM] Clear othercon pointers when a connection is closed

This patch clears the othercon pointer and frees the memory when a connnection
is closed. This could cause a small memory leak when nodes leave the cluster.
