9 suspend-to-RAM state (e.g. the ACPI S3 state).
12 bool "Enable freezer for suspend to RAM/standby" \
14 depends on SUSPEND
17 This allows you to turn off the freezer for suspend. If this is
18 done, no tasks are frozen for suspend to RAM/standby.
20 Turning OFF this setting is NOT recommended! If in doubt, say Y.
