Subject: [PATCH rcu 06/17] refscale: Always log the error message
From: Li Zhijian <lizhijian@...fujitsu.com>
An OOM is a serious error that should be logged even in non-verbose runs.
This commit therefore adds an unconditional SCALEOUT_ERRSTRING() macro
and uses it instead of VERBOSE_SCALEOUT_ERRSTRING() when reporting an OOM.
