From 490d20e65dd85628f910299a3925bbff466b2e74 Mon Sep 17 00:00:00 2001 From: "Vittorio G (VittGam)" Date: Tue, 19 Apr 2016 11:18:18 +0200 Subject: sleep: Add debug feature to bypass hibernation memory checks. (#3064) This new feature bypasses checking if a swap partition is mounted or if there is enough swap space available for hibernation to succeed. This can be useful when a system with a Solid State Disk (SSD) has no normal swap partition or file configured, and a custom systemd unit is used to mount a swap file just before hibernating and unmount it just after resuming.
