15 freeze tasks in cgroups before doing a suspend.
17 The common case is embodied in the freeze_thaw.sh test file. However,
18 the scripts are also designed to test a few obscure cases such as:
19 freeze self -- freeze the control group that the current process is
21 freeze cancellation -- freeze but then backout of the freeze processing
23 signalling freezing/frozen tasks -- this should delay delivery of the
25 vfork -- The vfork system call introduces an obscure special case for
26 the freezer kernel code. This test case attempts to trigger any
