/*
* Callout flags:
*
* CALLOUT_FLAG_ROUNDUP
* Roundup the expiration time to the next resolution boundary.
* If this flag is not specified, the expiration time is rounded down.
* CALLOUT_FLAG_ABSOLUTE
* Normally, the expiration passed to the timeout API functions is an
* expiration interval. If this flag is specified, then it is
* interpreted as the expiration time itself.
* CALLOUT_FLAG_HRESTIME
* Normally, callouts are not affected by changes to system time
* (hrestime). This flag is used to create a callout that is affected
* by system time. If system time changes, these timers must be
* handled in a special way (see callout.c). These are used by condition
* variables and LWP timers that need this behavior.
* CALLOUT_FLAG_32BIT
* Legacy interfaces timeout() and realtime_timeout() pass this flag
* to timeout_generic() to indicate that a 32-bit ID should be allocated.
