From 227c939b00cf786b5e2e95fc904518206f478421 Mon Sep 17 00:00:00 2001 From: Roland Dreier Date: Sun, 2 Apr 2006 14:39:20 -0700 Subject: IB/mthca: Always build debugging code unless CONFIG_EMBEDDED=y Change the mthca debugging trace output code so that it can enabled and disabled at runtime with the debug_level module parameter in sysfs. Also, don't allow CONFIG_INFINIBAND_MTHCA_DEBUG to be disabled unless CONFIG_EMBEDDED is selected. We want users (and especially distros) to have this turned on unless they really need to save space, because by the time we want debugging output, it's usually too late to rebuild a kernel.
