NAME
might_sleep - annotation for functions that can sleep
SYNOPSIS
might_sleep(void);
ARGUMENTS
None
DESCRIPTION
this macro will print a stack trace if it is executed in an atomic context (spinlock,
irq-handler, ...).
This is a useful debugging help to be able to catch problems early and not be bitten later
when the calling function happens to sleep when it is not supposed to.
