From ce0725f78a56a59bdb07cef003bc6fef722da38e Mon Sep 17 00:00:00 2001 From: Alexey Dobriyan Date: Tue, 5 Mar 2019 15:48:29 -0800 Subject: numa: make "nr_online_nodes" unsigned int Number of online NUMA nodes can't be negative as well. This doesn't save space as the variable is used only in 32-bit context, but do it anyway for consistency.
