From dd0393a5f29633f0e3d52e4c26ae4123c873c016 Mon Sep 17 00:00:00 2001 From: NeilBrown Date: Wed, 13 Dec 2017 14:15:55 +1100 Subject: [PATCH] staging: lustre: libcfs: discard MKSTR() macro This is only used for tracing when some strings might be NULL. NULL strings are not a problem for tracing, vnsprintf() will report them as "(null)" which is probably better (easier to parse) than an empty string. Also remove a nearby comment that doesn't relate to the (remaining) code at all.
