From d3cb26312ecfdb4ee8dedf931e24e60df1d7fbc9 Mon Sep 17 00:00:00 2001 From: "Paul E. McKenney" Date: Mon, 4 May 2020 16:40:53 -0700 Subject: [PATCH] torture: Remove whitespace from identify_qemu_vcpus output The identify_qemu_vcpus bash function can return numbers including whitespace characters, which can be a bit annoying in some bash dollar-sign substitutions. This commit therefore strips all spaces and tabs from the value that identify_qemu_vcpus outputs. Signed-off-by: Paul E.
