From 9250e523592a8ced3ecd14abe29fbb1e036bd7eb Mon Sep 17 00:00:00 2001 From: David Teigland Date: Mon, 9 Oct 2017 09:29:31 -0500 Subject: dlm: remove dlm_send_rcom_lookup_dump This function was only for debugging. It would be called in a condition that should not happen, and should probably have been removed from the final version of the original commit. Remove it because it does mutex lock under spin lock.
