From e8b5b191a55b7be671abf2c6d5d10db6edd8c1fb Mon Sep 17 00:00:00 2001 From: Dan Williams Date: Thu, 28 Apr 2022 15:10:16 -0700 Subject: [PATCH 157/217] util: Pretty print terabytes CXL capacities are such that gigabytes are too small of a unit for displaying capacities. Add terabyte support to the display_size() helper.
