Subject: [PATCH 1/3] dlm: fix a clerical error when set SCTP_NODELAY
Git-commit: b09c603ca40fc6980188f9c7f419c0918a3f461e
Patch-mainline: v4.18-rc1
References: bsc#1091594
There is a clerical error when turn off Nagle's algorithm in
sctp_connect_to_sock() function, this results in turn off
Nagle's algorithm failure.
After this correction, DLM performance will be improved obviously
when using SCTP procotol.
