I think a better solution would be a char device driver which has to be
kept open as long as a reference is held. When userspace closes it (be
that because the program has exited, been killed, etc) you can drop any
pending references.
OK, this interface is not intended for users/applications. It is
intended only for OMAP PM developers who are developing the PM code
and want to prevent idle for various reasons during development. It
is not intended for productions systems.
What about leaving /sys/power/sleep_while_idle but only if
CONFIG_PM_DEBUG=y?
Sounds like debugfs is the good place for this then.
