Raw Blame History

From 6e00430563108b98230abd7407ac54fde61ae93c Mon Sep 17 00:00:00 2001
From: Jan Synacek <jsynacek@redhat.com>

Subject: [PATCH] support ranges when parsing CPUAffinity
The functionality was implemented in https://github.com/systemd/systemd/pull/1699/.
However, it is not backportable without considerable code changes.
Implement parse_range() and parse_cpu_set_and_warn() from the upstream master
branch and use them in appropriate places. Also introduce relevant tests.
Resolves: #1493976
