[PATCH] ib_core: Enable and expose force_mr module parameter

Subject: [PATCH] ib_core: Enable and expose force_mr module parameter
Date: Mon, 15 May 2017 10:52:44 -0400	[thread overview]
Message-ID: <20170515145203.10708.16921.stgit@klimt.1015granger.net> (raw)

The fourth parameter of the module_param_named macro is a set of
file permissions. Passing 0 there means that module parameter is
not created and that adding "options ib_core force_mr=1" to a
modprobe.conf file has no effect.

The default setting of rdma_rw_force_mr continues to be 0, or false.

Fixes: a060b5629ab0 ("IB/core: generic RDMA READ/WRITE API")
