| /* |
| * 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. |
