28 | * Callout flags: | |
29 | * | |
30 | * CALLOUT_FLAG_ROUNDUP | |
31 | * Roundup the expiration time to the next resolution boundary. | |
32 | * If this flag is not specified, the expiration time is rounded down. | |
33 | * CALLOUT_FLAG_ABSOLUTE | |
34 | * Normally, the expiration passed to the timeout API functions is an | |
35 | * expiration interval. If this flag is specified, then it is | |
36 | * interpreted as the expiration time itself. | |
37 | * CALLOUT_FLAG_HRESTIME | |
38 | * Normally, callouts are not affected by changes to system time | |
39 | * (hrestime). This flag is used to create a callout that is affected | |
40 | * by system time. If system time changes, these timers must be | |
41 | * handled in a special way (see callout.c). These are used by condition | |
42 | * variables and LWP timers that need this behavior. | |
43 | * CALLOUT_FLAG_32BIT | |
44 | * Legacy interfaces timeout() and realtime_timeout() pass this flag | |
45 | * to timeout_generic() to indicate that a 32-bit ID should be allocated. | |
