From 07880fa4968b07db9df0f126bb7fbde245ed12ff Mon Sep 17 00:00:00 2001 From: Chuck Lever Date: Mon, 1 Oct 2018 14:16:06 -0400 Subject: svcrdma: Remove try_module_get from backchannel Since commit ffe1f0df5862 ("rpcrdma: Merge svcrdma and xprtrdma modules into one"), the forward and backchannel components are part of the same kernel module. A separate try_module_get() call in the backchannel code is no longer necessary. Signed-off-by: Chuck Lever Reviewed-by: Sagi Grimberg Signed-off-by: J.
